I've been going to Disney for years and I have had a chance to stay at all levels for resorts. I think the deals were much better in the past to stay at the higher price resorts including deluxe. I even did conceirge a few times with a deal.
I rather use the money difference doing a value over a mod to stay longer on vacation, eat at better places, buy more and better souvenirs, etc. We are hardly in our room; so, to clean up or sleep I think basics are just fine.
Now, if I won the lotto big time I may stay deluxe, but I would never do mods under any circumstances, now.
I agree with the other poster that the transportation system is very awkward at the mods. Also, I think of the mods as beeefed up values for a much higher price. Mods are my least favorite. Usually, for a little bit more you could stay at a deluxe AKL room and I would do that in a heartbeat over a mod, if I were do either one.
