it depends on your budget and what you want from your hotel. we love the dream castle, its very grown up, a bit of luxury but not the cheapest. we had 2 king size beds.
we really loved the explorers to, its busier and noisier but great fun for the kids. the pool has 2 slides and the life gaurds let you take the kids down them on your lap, and wait at the bottom to catch them. which were never allowed to do here.
