We also have a gas powered cart that we've used at the fort numerous times, no problem! (it is not fast, loud, or obnoxious) Have seen some that are though and use them all weekend long?!?
Sorry for the late info, I just joined here myself. As for the carts, I couldn't have cared less, my DH just didn't want to deal with charging the cart (or forgetting to do it after an evening at Crocketts Tavern) Gas or electric, you'll have a great time looping!
Who ever asked about buying an Golf Cart while in Florida, I would recommend Arts Golf Carts at 29630 US-27, Dundee, FL, 33838, 863-439-5431. We bought our Cart there last year and got good servicew and a good price. Also, they will deliver the cart to you.
