Knowing / accepting your budget / number of days.
If budget allows for a premier resort, take advantage so you get the express pass (shortest line). See stickies on the Royal Pacific Resort, Hard Rock Hotel, and Portofino Bay Hotel
Read up on stickies with the Annual Pass if you are going to be there for 3 or 4 days. It could save you money on hotel (look at the hotel rates stickies, too).
if the above is out of budget, consider other on-site hotels and read their stickies.
I've gotten so much out of the stickies on this board over the years and am very grateful for the helpful moderators and members.
