I am looking for a room only reservation at Disney World for August. I always have booked directly through Disney but this time, I decided to check out Expedia. I was surprised to find that I could get a value resort room for about $25 less and a moderate room for almost $40 less through Expedia. I have never used Expedia and was wondering "what's the catch?". Is it just as fine to use Expedia in stead of booking directly through Disney?
