I agree that the Movenpick looks more comfortable but we have stayed at the Explorers and found it to be very clean and comfortable, we are quite happy to return there. We only used it to sleep so haven't used the pool but those who have said it is OK. One point worth considering is that Explorers is first pick-up for shuttle bus for parks so you will have more chance to get a seat on the bus, bearing in mind that you have a 4 year old I would think you would consider that is quite an important point. On saying that, the Movenpick is second pick-up, it was the ones at the Kyriad I always felt sorry for!
