We had ressies for the same time period-Dec 4-7 at ASMo, then Dec 7-11 at Poly GVC, but after all I've read, I ended up switching to WL for Dec 4-7. This is our first trip, and although I KNOW my 2 DD (ages 5 & 8) would LOVE ASMo, I don't want to take chances on experiencing similar situations that I've read about-kids running up & down the halls at all hours, pools being very crowded, bad language being used, etc.
To be fair, some people have written that they stayed in the Love Bug section and didn't have as many problems, except for the food court being crowded in the morning.
Just my 2cents...
