There are so many RV Parks in and around Houston.
Go to Bing Maps
. Type in the Bing pane "houston, tx" without the quotes. Once Houston appears then type in "rv park" without the quotes. The map will be populated with some RV Parks in the area. Drag the map around and the parks will repopulate the map.
There is a new park called Advanced RV Park at the area of Beltway-8 and Highway 288 (Welcome to Advanced RV Resort
) It is relatively new. I stopped in there the other day to look it over as a possible recommendation. It is 10 miles South of Downtown Houston from I-10. (I-10, US59S, South Freeway-288S) You can use the Beltway (toll road) to get to PPL, and I-10 to Katy for CW.
We live 40 miles from Downtown Houston. There are a lot of RV parks in this area. Green Caye, in Dickinson, TX is nice and caters to Winter Texans. There price is $370 a month and includes Electric (last I knew) Dickinson is about 30 miles from Houston.
Dickinson to Katy (where CW is) is approximately 60 miles. Dickinson to PPL is approximately 40 miles.
Dickinson to Galveston (sight seeing) is about 20 miles.
