We just recently bought a pop-up trailer off of craiglist and are very happy. We used to tent camp, long ago, but have decided we like having a little more comfort! Our pop-up has AC, heat and a water heater, so very comfy. We've only gone a couple of times, but really enjoyed staying at Lake Lavon last week. The lake is full and our son enjoyed fishing (he's almost 4) and playing around the water.
There are places to go around the metroplex, you just have to expand your thoughts of what you might want to do! We were used to large wooded campgrounds, and you don't find much of that. But, we want to get our son out to appreciate nature and other things besides TV and video games (yes, it starts early).
Good luck deciding! We went with the pop-up so we would be unhooked and could go other places from the campground, but that was just our thought!
