Eastern Ontario, Canada, to LRGV in January

Travelers World. Take the bus to the river walk.

This is also where we have stayed for visits to San Antonio, though we did not take the bus. We drove downtown and parked in a lot, but I hear the bus is convenient. Mexican restaurant across the highway.

In case you might want to visit the Texas Hill Country (Fredericksburg, Kerrville, etc) there is a big RV park out north of San Antonio at Boerne (pronounced BURNey). I believe it is "Alamo RV."

Since you are staying in San Antonio you can probably drive right on down to the Valley, but we often bypass San Antonio and stay at the Choke Canyon State Park (Callaham Unit)--lots of wildlife and on a lake.
