Senate Majority Leader Harry Reid, D-Nev., may have kept members of Congress from their scheduled vacation this week, but several legislators have big plans for the upcoming weekend. At least 13 lawmakers will be skipping town tomorrow to attend annual fundraisers.

Sen. Pat Roberts, R-Kan., will be making the long trek out to California for his annual “Napa Valley Wine Tour.”  This will be at least the third summer in a row that Roberts has held such an event. The privilege of sampling the best of the vine with the senior senator will cost an individual attendee $2,000, while a PAC may host the event for $5,000.

A little further north on the West Coast, Rep. Earl Blumenauer, D-Ore., will be spending the weekend in Portland for his annual “Pinot in Portland” event. Like the Roberts event, this too is an annual fundraiser going back to at least 2009. While the invitation features a lovely silhouette of the chairman of Congressional Bike Caucus on his ubiquitous bicycle against a backdrop of the Portland skyline it does not give away many details about the event, such as location or cost. Last year’s invitation was equally beautiful and vague, but the invite from 2009 suggests a donation of $5,000.

Political donors looking for a fundraiser closer to the capital might consider the “Annual Chesapeake Weekend Retreat” benefitting the Blue Dog PAC. Party Time has invitations to an annual summer retreat for the conservative leaning Democratic caucus going all the way back to 2006. Each year, the event is held at the Hyatt Regency Chesapeake Bay Golf Resort in Cambridge, Md. The price to attend is $2,500 for an individual and $5,000 for a PAC.

No doubt on a quest to reduce the deficit by winning big at the slots, a group of 11 Democratic house members will be heading to the Foxwoods Resort Casino in Connecticut for the weekend. The event is a fundraiser for Rep. Joe Courtney, D-Conn., who will be bringing with him the entire Connecticut congressional delegation on the House side, as well as a few Democratic colleagues from other states. It’s not clear if the outing is an annual event but Party Time does have an invitation to a near identical fundraiser from 2009 featuring a similar set of lawmakers. That fundraiser took place down the road from Foxwoods at Mohegan Sun. Both casinos, some of the largest in the world, are required to contribute 25% of their slot machine earnings to the state of Connecticut, a figure regularly in the hundreds of millions of dollars. The weekend at Foxwoods will feature a dinner with “Casino 101,” golf on an exclusive course, and a “festive evening boat ride” featuring a fireworks display. Contributions for the event are listed as $2,000 for an individual, $2,500 for a PAC attendee, and $5,000 for a PAC sponsor.

If you’re still in town, there’s a relatively cheap opportunity to schmooze chiefs of staff for several powerful GOP senators tomorrow at a “Dog Days of Summer Cookout” benefiting the National Republican Senatorial Committee’s offices.

The cost is just $100 per individual–a bargain compared to most fundraisers we document here at Party Time–and the attire is casual.

The chief-of-staff lineup includes Jackie Cottrell, who works for Sen. Pat Roberts (R-KS); Rick Dearborn, for Sen. Jeff Sessions (R-AL); Beth Jafari, for Sen. John Cornyn (R-TX); Billy Piper, for Sen. Mitch McConnell (R-TX); T.A. Hawks,  for Sen. Thad Cochran (R-MS); Kyle Ruckert, for Sen. David Vitter (R-LA); Michael Schwartz, for Sen. Tom Coburn (R-OK); Ryan Thompson, for Sen. James Inhofe (R-OK); David Young, for Sen. Chuck Grassley (R-IA); and Matt Zabel, for Sen. John Thune (R-SD).

The Huffington Post’s Arthur Delaney was on hand this morning outside a breakfast fundraiser for Senators Pat Roberts (R-KS) and Chuck Grassley (R-IA) at Charlie Palmer Steak house:

Standing by the door at the start of the event, Grassley declined to say who might be attending. “You’ll have to ask Senator Roberts,” he said before walking inside.

Guests politely declined to identify themselves as they arrived. But one, a lobbyist representing the American Association of Crop Insurers, forgot to remove his name tag when he left (Sen. Roberts sits on the Senate Committee on Agriculture, Nutrition, and Forestry).

Asked what was discussed during the breakfast, the man said it was health care. He said Sen. Grassley did not discuss his upcoming meeting with other Finance Committee members — the so-called “Gang of Six” — and President Obama later in the day.

When Congress is in session, lawmakers do most of their fundraising partying at a handful of Washington hot spots clustered close to the Capitol building. With members of the House already on recess and the Senate soon to follow, however, lawmakers are taking their parties to far-flung locales, from Aleyeska Resort in Alaska to California’s Napa valley to Jackson Hole, Wyoming.

• On August 14, Sen. Mark Begich (D-AK) hosts an event benefiting his leadership PAC, Great Land PAC, at Alaska’s Aleyeska Resort. Activities include hiking, bike riding, fishing–and, but of course, gold mining. If your PAC pays $5,000 for a space, that amount will apply to all Great Land PAC events for the rest of the year.
• Sen. Pat Roberts is venturing far from the plains of Kansas to the valleys of Napa. On August 8, he welcomes donors to a wine tour; cost is $5,000 for a PAC to host, or $3,000 per PAC or individual to attend. The next night he hosts a dinner benefitting the National Republican Senatorial Committee (NRSC) at the farm at Carneros Inn.
• On August 10, Sen. John Barrasso (R-WY) is hosting his second annual “Teton Tee-Off” at the Jackson Hole Golf & Tennis Club. Cost is $2,000 for a PAC or $1,000 for an individual–but does not include green fees. And Sen. Judd Gregg (R-NH) is joining Sen. Mike Enzi (R-WY) on August 13 for “a day in the Tetons (fishing & dinner)” for Making Business Excel PAC, Enzi’s leadership PAC.
