We got lucky and came here on a beautiful cloudy day 1.5 hr before closing time. We rented the Electric Pontoon which fits 10 people for $90 an hour. This is a GREAT deal, so we ended up getting it even with only 3 of us. We had a blast!! There were other water rentals around us in the water - kayaks, paddle boards, pedal boats, etc so we had to be careful since we were the biggest boat at the time. We needed to leave one driver's license and a credit card while we had the boat.
Customer service was alright. Staff weren't enthusiastic but not rude either. They sell a few snacks (chips, gummy worms, cold drinks, ice cream) you can take with you. Parking was a little packed but we got there just in time.
Will definitely be back here as it cools down to do other rentals!
