Here are my opinions on the advantages/disadvantages of each level:
Advantage of Value over Moderates and Deluxes
* Price.
* Food Courts for quick meals.
* Pop Century has its own bus.
* All Stars resorts share busses, but there is usually very little wait on either end.
Disadvantage of Values
* Small rooms.
* Large groups can sometimes be rowdy.
* No pool slide or hot tub.
* external corridors.
* Pizza delivery only.
Advantage of Moderate over Values
* Nicer feature pools with slides and hot tubs.
* Bigger rooms.
* Sit-down restaurants (all but POFQ).
* Real bars in main area plus pool bar, not just pool bar (except POP).
* Nicer food court, it's not just one big room.
* No giant icons.
Disadvantages of Moderates
* Can be spread out and most need an internal bus system.
* External corridors.
* Pizza delivery only.
Advantage of Deluxe over Moderates and Values
* Bigger rooms yet. Many can sleep 5 people.
* Large variety of sit-down restaurants.
* Nicer feature pools, many with zero entry.
* Internal corridors.
* All have sliding glass doors and most have balconies or patios.
* Most have special proximity to parks: monorail/boat to MK, walk/boat to
Epcot/MGM.
* Room service.
* Valet parking.
Disadvantage of Deluxes
* Epcot deluxes do not have snack shops for a quick meal, except the Beach Club Marketplace.
* Price.
* Busses are often shared, especially the Epcot resorts. The ride can take a long time.
* Self parking can be difficult, especially at the monorail hotels.
