I thought fast pass was the best money I ever spent. The lines vary from day to day and even at different hours within the day! You CANNOT take anything AT ALL on some of the rides- no water bottle, no backpack or purse, NOTHING. This is strictly enforced, so make sure you rent a locker (at multiple places within the park, we used the ones by the train to Hogwarts, but it was crowded and I would suggest finding another) BEFORE you get in line. You may want to check a travel site like trip advisor.com for more info, you will probably find more info on that site than on a Marriott site.
