I do you accep the RV to stay all nignt on you site? Tank you,

I see RVs there every day in the summer

Many Walmarts are beginning to discourage this and despite what some may say, it is not acceptable at every location. You can Google to get a list of which ones currently do, but the best approach is simply calling the customer service desk and asking. It is also best to "check in" up on arrival to avoid that 2 a.m. knock on the window. Also, grab a little something from the store so you at least patronize the location and keep them from frowning on future campers.

I am not sure.

Security doesn't allow that.

I believe you can
