There are over 500 parks in the RGV so definitely something for everyone and every price range.
We stay at
Victoria Palmsin Donna Texas which is pretty much mid valley. So not too far from anything.
We have a new Walmart less than a mile from our park. Don-Wes flea market adjoins our park. Dollar General very close.
A nice little Border town Nuevo Progresso where we have all of our dental work done is maybe 5 miles. Lot's of good restaurants and fun shopping in Nuevo Progresso.
There are all kinds of specials for first time visitors at Victoria Palms.. :W
Tell them Ron & Shirley 2371 said to check them out. :)
Wherever you end up enjoy your winter.
