Hi, I'd like to take my kids aged 5 and 8 to somewhere like Spain or the Balearic islands, ideally somewhere with or near a waterpark, but every time I find somewhere that seems perfect I go on trip advisor and see people moaning that the beds there were rock hard. This happened to us in Majorca a couple of years ago and I don't want to suffer it again, it was awful, like sleeping on the floor. Any ideas please of child-friendly resorts with comfy beds!
