mixed answers will be posted on this question probably, all based on personal experience.
usually, the ap rates are better than
aaa, depending on the time of year you are going.
for october, usually aaa rates are the best but sometimes the ap rates drop in september and it beats out the aaa deals for that time period.
you qualify for the loews welcome gift/upgrade if you book w/aaa.
some have stated they do not get the amenities when they book w/ap
it is set up for a loews member to only get the entitlements when booking with anything other than the ap. sometimes they do, sometimes they don't
you ask which is better? i have aaa and get the 10% discounts and hotel discounts. i have the universal mc which also gives the discounts.
i am seriously thinking of upgrading my 5 day pass to an ap as it has benefits that are great. free parking, food/merch discounts at a higher rate than aaa or mc, discounts on
hhn tickets, specials during the year.
