I'm always skipping Tom Sawyer's Island and the Riverboat. I think next time I go, I'm going to try them out.
If you love WDW and plan to go back often, my advice is save some things.
My most recent trip I did the Fantasia Mini Golf (what a blast!), the Behind the Seeds tour and saw Tinkerbell flying around her shop.
There will always be new rides, but I plan on trying to save some of the little out of the way things to have something special on each visit. That way too my wife and I can experience new things together since I have been more time than her.
