Not having stayed in values or mods, I can't answer that part of the question. I can however tell you that our reasons for staying Deluxe are:
1)
Bed size. DH is 6'3" and I don't care who says you can fit a guy that tall in a full size/dbl bed AND allow for another person... well, in 19 years we haven't found
that double bed. That and the
day bed-- even though I have 2 girls, the 50 minutes we spent listening to them argue about
who was on who's side at the Hampton Inn in North Carolina, on the ride to Florida was NOT worth repeating!!
2)
Room size. We drive, never fly anywhere, and therefore have more 'stuff' than many who might fly. That and we stay for at least a week, so we like the feeling of being able to have our own space. The rooms at the Poly are big. In Tahiti they were huge! 476 sq. ft.
3)
Inside corridors. Important to me. Personal thing, no bad experience, but a number of outdoor corridors in the past with light showing all around the doors and noise from such. I sleep better in a building with inside corridors. That simple.
4)
Transportation. No matter how great people say the busses are from the values or mods, I don't want to try. We spend 50% of our time in MK and Epcot and so being on the monorail works for us. It lets us escape the parks quickly too.
What
doesn't matter? Cleanliness, food choices, theming (only to the extent that I think all of it is great), pools (do they have water?? OK.), "kid" or "adult" themed means
nothing. They are everywhere...we even bring two ourselves
.
I think all of the WDW resorts seem great for one reason or another. If we could get Queen sized beds I'd even stay at a different resort for a few nights.
