we never had a problem with any level of resort room. In all honesty, the rooms may be a little smaller, but mods and values have the same furniture, so you basically have the same seating arrangements. For the amount of time we are in our rooms, we stay NOW at value,we started at Deluxe, but moved our way down - kind of opposite of most people, as we appreciate having the extra money to splurge on other things. Once we did the V&A Chef Table and that one meal cost was more than the room for the vacation - yes, we are different. Back on topic....
If you will spend lots of time in your room go for the Mod, if not a value should be fine in our opinion.
