Last 2 Disney trips we have stayed at mods. and it would be very hard to go back to value. But I do have to say that to my kids....POP will always represent Disney to them. It's larger than life, colorful, Lady and the Tramp statues, Goofy water-play area and much more. The pools at the mods are much better b/c of the sildes. Will never go back to the values due to the noise levels, small rooms and HARD beds. But POP is big on theming, but the pools are better at the mods.
Good Luck!
