I got mine over a weekend in September at Jack Brown's Seaplane Base in Winter Haven, Florida. Jack Brown's Seaplane School, Winter Haven, FL

It is $1,200 to add on the ASES. It includes 5 hours of dual and the fee for the checkride. You will have to pay more if it takes you longer than 5 hours, but if you are regularly flying then it shouldn't take longer. And I agree that it's the most fun flying that you can do!
