Geez, these trips are making me feel like I'm a slacker as a leader! We try to do one overnight trip each year. So far we've done Miami Seaquarium, Miami MetroZoo, a dance studio right in our town and Coco Key in Orlando. Orlando was our farthest trip (3 hours), but it wasn't too expensive. Our girls aren't big on selling the nuts/candy and I'm always the one pushing hardest on cookies so we don't make a ton of money - usually around $1,000 for both sales.
This year I think we're going to do an even smaller trip, but are going to try to earn our bronze award so I'm assuming they'll vote to use lots of their money to go towards whatever service project we pick. Who knows though - they might pick a service project that requires more work then money and want to go on a big trip!
In the back of my mind, in case they do want to do a bigger trip, I've been thinking about Savannah, Disney for the 100th anniversary of GS and Sea World. There is a GS camping ground in the Keys that I'd like to learn more about, but neither of us have our camping certification so we'd have to recruit another leader to come with us.
