I've only been to POP, but here are my personal pros & cons for that one
GOOD:
*CHEAP
We stay in 2 rooms for less than the price of one room in a mod or deluxe. They are small, but the ability to close the door to the kids' room at night & watch tv is crucial for my sanity.
*Food court is good, IMO. There's a good variety, and the food is tasty. We seem to eat 2-3 dinners there and a few breakfasts as well.
*bus service to resorts for us has been great -- we go in Dec. though, so take that with a grain of salt if you are planning for a busier time.
*Magical Express:: FIRST OFF, LAST ON! Love that, and with young kids, it's worth its weight in gold, especially on the ride to the airport when everyone is tired from the long trip.
CONS: (these are likely for all values, but my thoughts anyway)
*external doors. I don't like the "motel" feel, but I've also never felt unsafe there, like I would at a regular hotel. the magic of disney spreads for me, I guess :lol:
*definitely not "nice" accomodations. Perfectly adequate, but no luxury. I became a bit of a hotel snob before I became a SAHM because I travelled for work & stayed at nice places. With kids, I have to give that up. But it's very ordinary. Small, not so great beds, carpets that have clearly seen their share of wet feet from the pool. Small rooms.
But I'm going back for the third year in a row ... so the cons can't be that bad
My DH is, um, frugal
so while *I* would love to stay at a nicer resort, we'd never go if I insisted. I give up on resort quality in order to convince him to go more often!
