Just an FYI, we rented a sea raycer one day, and a pontoon boat a few days later. On the day we rented the pontoon we found out there is a AAA discount (that we didn't get on the sea raycer because we didn't know and they didn't mention it). My 12 year old twins enjoyed driving the sea raycer!
So if you have AAA ask for a discount, or ask if there are any other discounts available.
There is a 20% coupon for the fishing expedition in the back of the Birmbaums guide to Disney.
