Hi 2gs...if there is a decent 55+ park in the Rockport area, I haven't been able to find it. Found one deeded community at 55+ but realtor does not respond or return calls. Two others, both slide to slide. Literally, looked at one with 15" between slides.
Several very nice parks in this area, Coastal Breeze is a fave, but not 55+.
Update: took an overnight to the RGV! Viewed several mentioned parks here, including the famed Retama Village. It is very nice. However, the "rv resorts/parks" are mostly old, tired and 90% mobile homes. Some were neat and clean, others just scary. All friendly. Have found a couple that would do for a short time, but most are slide to slide. Rates good, but again, tired. May go back down again for a day or two and hunt some more. Definitely don't want to be on the Coastal Bend during the summer months. Even though I broke down and bought a fishing pole. ??.
