Here is a link to the Hitchin Post web page:
Hitchin PostIf you have adequate air conditioning you could consider this, but that would certainly be a personal decision.
We have two ACs and have stayed at some of the hottest places in Texas in comfort. Could not do it with one.
We have never stayed at Hitchin Post because it's only about a half hour from our house, so I'm not commenting on the park itself.
Let me know if I can help with information about Hallsville, Longview, Tyler, or East Texas in general. I've lived here all my life.
