I did look at the Aerobeds and they look fantastic. However, I bought the Coleman Comforts along with a 12v pump and they go up in about 20 seconds, so as you only do that once (hopefully they won't go down), it doesn't seem to be that much of an advantage.
Plus as I was looking at four beds, the Aerobeds would have given me four pumps to store (and pay for).
Probably worth it if you are just after one double perhaps.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
