OMG: There is SO much more to do!!
Tours:
Keys to the Kingdom - awesome and reasonably priced tour
Animal Kingdom tour - forgot the name, but it's supposed to be great. You get to rope climb over the
Crocs, and there is even a private lunch that looks over the safari
Animal Kingdom Lodge has fantastic activities, plus Boma is a great place to eat. If you want a more adult eatery, then check out Jiko. AKL has activities like wine tasting, cookie decorating, safari night viewings, African drumming, animal rubbings - great cultural interpreters - so much to do there.
Mini golfing!
Pontoon boating and mini speed boats. Love the mini speed boats!
Going to the top of the Contemporary hotel and eating either dinner or just going for drinks and appetizers in the lounge. Caveat: dress up a little for this, since Disney now has CM "gate keepers" on the fourth floor who makes sure that people are neatly dressed and not just slumming it up from the pool.
Going to any of the eatery lounges for drinks and appetizers. I am not a drinker, but I love going to the lounges for snacks and stuff with my family - we have a great time.
Grabbing fish and chips and eating by the Beatles cover band in England.
Playing the Sorcerer's Apprentice game at MK, playing the Agent P game in Epcot, decorating Duffy at Epcot. One year, I sent postcards signed by CM from each county at Epcot to my BF back home. You can also get autographs signed by CMs in each country - I did it, of course I was in high school and I picked out super cute guys to sign them. Idkw, hey, I was in high school!
Get a "Happy Birthday" pin, but write "Un-Birthday" on it. See what happens.
Actually go swimming at your pool instead of looking at it! Spend a whole day at your resort - we always forget to stop and stay at our hotel, you know?
Watch the Electrical Water Pageant. Preferably from the top of the Contemporary resort. Watch wishes from the Polynesian beach. Or do the Wishes dessert party. That is a great party!
Visit the Rose and Crown in England - the pub and the restaurant are good.
Get margaritas in Mexico, pretzels in Germany, a Dole whip in Adventureland, climb the Swiss Family treehouse, get some brew and a lambshank at Gaston's, listen to the piano player by Casey's!
Take the pontoon boat from PO to DtD and back again. Get beniets, gumbo and po'boys at POFQ
With regard to Uni - London and Diagon Alley are going to be AWESOME!!!

Unless Diagon Alley and London aren't open or don't appeal to you; there will be a need for at least a parkhopper. London is in Universal Studios and Hogsmeade in Islands of Adventure.
Gosh, there are lots of things to do!
Have fun!!!
