Just a heads up - if the area is already saturated, and if it's an area that experiences any kind of dearth, you need to be ready to handle complaints about bees on peoples' soda cans, bees after the garbage cans, and in their dogs' water dishes. These locations will all be visited with varying frequency.
I hate to sound like a party-pooper, but your enjoyment of beekeeping at this location may lessen. Try to keep the situation going in a positive direction, but be ready with a backup plan.
I mention the soda can because it's worth noting. I had a party here at my place a few weeks back, and we were in the middle of a dearth. Bees drinking from the lips of soda cans didn't phase the president or vice-president of our local beekeeping organization, who were among those attending, but it did make me think - what if *somebody* didn't look first, or got one in a can. You and your family may be cognizant of the risk, and always prepared for it, but the folks at this RV park might not be as educated as you are. You might want to check and see how well covered you are with insurance...
