Differences between Deluxes and Mods:
- All Deluxes, except for AKL, offer direct, non-bus transportation to at least one park. No mods offer this. POR/FQ offer a boat to DtD, but not to a park.
- Most Deluxe rooms offer either a patio or balcony. Depending on the resort, or room locations, the balconies can vary greatly in size and view. From what I gather, Mods do not offer balconies in their rooms. If I'm incorrect, please post, as I'm not certain of this.
- Some people might say there is a difference in theming, or the "magic" of the places. I disagree with that, and think Pop Century is probably as well themed and magical in its own way as the GF. It just depends on your tastes.
That's about it, really, as far as major differences between the 2 tiers of resorts, except for price of course

. The balcony thing isn't that important to us, but the non-bus transportation to at least one park really spoils us for Mods.
You mention you don't spend much time in the room when you're not sleeping. If this is the case, you might well be saving a lot of money you don't need to be spending on views, etc. that you pay for at Deluxes, by staying in a Mod.
The only drawback, if you consider it a drawback, is the necessity of taking the bus to all the parks, instead of one park accessible by boat, monorail or foot.
