POP is closest. You can see the lighting at WWOS from the resort. They are on opposite corners of an intersection, but both sit back so it's not like you can walk safely from one to the other. You can drive it in a couple minutes.
Our sports group is staying at POP in March and there are cheerleaders staying there this month. They are paying rack rate, but the price at AllStars last year was a minimal discount . I think it will be well worth the extra to be at POP.
