I have gone to all the airshows for several years and the best IMO is Sun N Fun at Lakeland and AOPA at Tampa or Palm Springs. I do not like Oshkosh at all....to expensive for hotels, not enough support from the community, little to do before or after the show (in the area).
I would Skip Oshkosh but not Sun N Fun. It is a blast plus you can take an extra day to do Epcot, Seaworld, go to Miami South Beach or fly to Key West.
I plan on going. If people are serious about meeting up they should swap cell phones so they can text mssgs back and forth to hook up. It is extremely difficult to meet people you do not know, do not know what they look like. So you sit around saying are you with this one or that one and feel like an idiot so you stop and don't hook up.
The other option is for each person to agree to get a specific (non aviation related hat) and then wear it the first day to identify each other. If everyone got a red Tractor Supply Cap or hooters or what have you. At least you narrow down the strangers you have to ask.
I usually meet a group of guys and we agree to stay at the same hotel so we see each other for breakfast or dinner the night before.
