OK, here is my $.02.
Golf carts are great & I always carry mine, but if I had to choose between a cart & a car, I would choose the car. The carts can only be used on FW property. It is fun to have a cart to go 'looping' especially during different holidays to see the decorations. The carts can also save time by not having to rely on the internal buses to get around inside FW. If you do bring your gas cart, remember there are no gas pumps at FW. We did a tow vehicle with bicycles for many years before we got a cart.
Full & Preferred campsites are basically set up the same way. They have a paved pad to park your camping unit & it is surrounded by a crushed shell/sand mix that you can put a tent on if you wish. Preferred sites are closer to the Settlement area at the North end of FW and puts you within walking distance of the FW landing to catch a MK boat or a boat to Contemporary or WL. Also in this area is Pioneer Hall, Crockett's Tavern, & Trails End buffet.
The Premium sites upgrade started a few years ago. FW like any other resort, was do for an upgrade. Many of the rigs today are longer & wider (slideouts) than FW was originally designed for, so they took many of the loops & upgraded them. They basically took these full hookup sites and laid additional concrete over the areas that previously had the crushed shell/sand. If you are planning on using a tent, there are very few premium sites that have enough room to stake out a tent.
They have also been upgrading the electric service at the sites, the original hookups that look like tree trunks are wearing out & being replaced with the standard metal service panel pole.
The photo at the bottom is me on a premium site in the 900 loop.

For the most part, you can park or place anything on the paved or shell covered areas, but if you park anthing on the grass, there is a good chance you will be asked to move it.
