we, too were in this quandry.. we booked AOA. the LM rooms were the only ones which fit our needs (just 2 adults).. of course, non of the discounts were available for the LM rooms.
when the discount came out, we consisdered switching to POR. we would really want the mansion rooms.. but there's no guarantee. and th elast time we were at POr, we were SDo far away from the food court, etc.
and then we thought about the theming.. and the very colorful cheery themeing at LM. and the rest of AOA>
then tried to picture ourselves at POR. looki around,. what do you see. are you happy with what you see around you? or are you wishing you were lookinhg at Ursula? Ariel? simba? Rafiki? the Big Blue? nemo, the Carsland, etc. etc. etc.
do this mental exercise, and you will have your answer.
