Don't know how familiar Ya'll are with New Braunfels and the Guadalupe, but River road is a major tourist area. We see 15-20 thousand tourists every weekend through the peak season. (Memorial day through Labor day), twice that number on holiday weekends! That being said there are some options I can suggest. Many of the campgrounds located right on the river are extremely crowded and often reserved a year in advance, making it difficult to get many sites located together. There are other camping areas located upstream from the most popular areas (un-advertised local secret), where there is limited access to the river for tube/raft/kayak outfitters. Making for a less crowded experience. A couple of these places have great accommodations, ie: electric/water hookups shower/restrooms. One has a rather large group pavilion with about a dozen picnic tables under it. These are popular with scout and church groups. This would easily accommodate 15-20 trailers. Down side here would be that to float the river at these areas you have to provide your own "shuttle" service from the less frequented parts of the river. (haul the rafts/tubes and people yourselves). They do offer shuttle service to the more popular/crowded areas. I will check with them to find out about available dates. I'll also check with a place called River Road Camp
http://www.riverroadcamp.com although they are in the middle of the crowds and very popular, and might not be available for a gathering until after labor day. I guess I'll just check with several places that I know about first, and see what's available when and then folks can decide.
Anyone thats interested, let me know your thoughts
Sorry this got a little long!!
