We just got back from an 8 night stay at ASMo yesterday - me, DH and our 2 and 3 year old kids. This was our first stay at a value resort, and our previous stays had been at WL, CSR, the Swan and Poly. I liked ASMo and would do it again.
Having read the boards and UG, I was prepared for a tiny room and braced myself when I opened the door. I had already told my husband that if we hated it we could try to transfer. But that was not the case. I didn't feel the room was small at all - it worked for our family just fine. In fact, other than a double sink, the room didn't seem any bigger to me than the other rooms we stayed in.
We don't spend much time in the room or at the resort. We're out of the room around 7 or 8 a.m. depending on what park is having EMH and we sometimes come back for a nap for the kids (staying 1-2 hours), and then we're back out for dinner and return in time for the kids' bedtime at 8 or 9 p.m.
The kids loved the theming at ASMo and so did I. We didn't walk all around the resort, but the giant Buzz and Woody characters in our section were awesome. They had a great playground for the kids and a nice kiddie pool as well as a big pool in our area. I thought the food court was really good - lots of variety to suit everyone's needs. Burger, shicken sandwiches, salads, good pastries and cookies. Lots of beverage choices. Great alcoholic drinks for DH and I at the pool bar. The gift shop was large and had lots of cool stuff.
Mousekeeping for our room was outstanding. Being in the Toy Story building, we were pretty close to the food court and bus stop - no complaints about that at all.
Transportation-wise, we never had any problems with the buses. They came quite frequently and we never waited more than 5 minutes at the resort for a bus and no more than 10 minutes at a park. Ride times to the parks from ASMo were not long at all like I had imagined. We also liked the convenience of taking a taxi to AKL from ASMo to hang out and eat at Boma. The fare was only $7.
I would say that if my kids were older, I might wait for a code and get two adjoining rooms instead of trying to all stay in one room. I can see it being cramped for a family of four with pre-teens or teens. But if you get a code for $59, getting two rooms isn't bad at all.
Sure, I love the Poly and having seen AKL I would love to stay there too. The restaurants at both are outstanding and they have activities for the kids. But when I go to WDW, we go to the parks so I'm not sure the extra money spent on the hotel would be worth it.
That's my two cents.
