Hey Sean, Im just back from OBA, the weathers pretty warm at the moment so im guessing by the time June comes round it'll be even more roasting! I managed to get sunburnt even just preflighting! Definitely do loads of studying now, if possible get a few exams out the way before you go over, and if not then try to get them out the way asap when you get there because by the time your solo / cross country flying starts the last thing you need is to be constantly studying too. In 3 weeks there I know of at least 4 people who were sitting their Nav exam just hours before their skills test! It can all get pretty stressful if you leave the exams too long.
As for bikes just grab one, though chances are wherever it is you're staying they'll already have a few stashed in the garden. You dont need club membership to eat at the golf club. Its really nice and you get a decent lunch for about $7. I didnt budget per day for food/drink, about 6 of us lived together and we'd just go to walmart n all chip in for all our food and then eat whatever, worked out pretty cheap that way and lasted ages.
If you got anymore questions feel free to pm,
