We have a 40' motorhome with 4 slides, so we always get a premium site. Premium sites are wide and the concrete slabs are longer than others. Actually, there are four categories of campsites at FW, premium, preferred, full-hookup, and partial. The following is from AllEars.net site:
The Premium Site is billed as "big-rig" friendly. They accommodate RVs larger than 45 feet in length and those that have multiple slide outs. The sites are wider (up to 24 ft), and deeper (up to 60 ft) meaning they have a larger, level-paved pad. They also feature all of the amenities - water, power, sewer, cable, and access to the high-speed Internet, plus upgraded picnic tables and grills as well as prime locations.
Tent campers can use premium sites, but since they have a full pad with no sand area at all, unlike the preferred, full, and partial, it can be impossible to find a place to put in tent stakes. The actual size and shape of each site "will depend on Mother Nature", as Disney likes to say.
To Disney, preferred sites means those that are located near the Settlement Trading Post, Pioneer Hall, Meadows and marina areas (meaning the preferred/in demand areas). Preferred Campsites include: water, power, sewer, cable. Internet Access is free. There will be a $125 deposit hold on credit card. Once kit is returned the hold will be released). Campsite sizes vary in length and width and some can accommodate equipment up to 10' X 60'.
Sites in loops 1600, 1700, 1800, and 1900 have been equipped with cable and Internet, but due to their location, will remain Full Hookup.
Loops 1500 and 2000 remain as partial hook-up sites for campers using tents, pop-up campers and van campers. As now, RV will not be allowed on these sites. All sites include cable TV and offer high-speed Internet access. Picnic tables and grills will remain as they are now. As of now, there are no pet loops in this category.
Hope this helps. We'll be there October for a week in and December for 8 days. Can't wait!
