Great to see some of youse are coming this year
The hotel right on the airport that DUXNUTz mentions is the Hilton, rather than the Marriott. As you can imagine, rooms there don't come cheap.
For accommodation links & suggestions, the Oshkosh Convention & Visitors Bureau -
EAA Lodging, Accommodations, Short-term Rentals, Houses, Camping, Hotels, Gruenhagen - Visit Oshkosh is very helpful. Also, check out craigslist -
appleton apts/housing for rent classifieds "eaa" - craigslist A lot of people have been posting on there offering rooms in their homes, or the whole home to rent.
There is multiple entertainment on every evening, ranging from private parties through Theatre in the Woods to the fly in movie theatre to type group club gatherings to chapter gatherings to lifetime member gatherings. And of course the night airshow - fingers crossed for the weather again this year! Suffice to say, you shouldn't be short of things to do in the evenings.
If you haven't been before, try to make a stop at the seaplane base (just remember the mosquito juice), I doubt you'll be disappointed. The watermelon social -
Watermelon Social is well worth going along to - great food and fun atmosphere.
AB - You may find some answers to your questions on oshkosh365.com in the AV section. Camping on the grounds is definitely the way to do it. The campgrounds go from a very large, empty space for 45 weeks of the year, to a small city of about 30,000 to 40,000 people for the main week of AV. 99% of folks there are happy to help if you have any questions or issues.
Or pm me if you have any other questions.
Look forward to seeing you at the International Party
