I think you're really going to enjoy BB. As for rental prices, you should contact Monkey Business and I'm sure they can tell you for sure, but I seem to remember bikes were like US$5-10 a day. Golf carts could be rented for as little as one hour for US$10 or else I think they were like $65 for a full day.
Local news here in Mpls sounds like you guys got two feet of snow last week. Bet you can't wait to hop a plane... Have fun!
