Hi Lesrs
I stayed at the Louis Creta Princess, July 05. It's a really nice hotel for families, in pretty grounds. The pools are beautiful, the food great, and so are the animation team. Family rooms are a bit on the small side, with 2 twins for the adults and a small bunk bed for 2 kids. It's beachside but the hotel beach isn't brill, although we did ringos, banana boat and canoes from it.
I did put up a review which hopefully is still there. (Chris from London)
It's a bit isolated though. The nearest village is Platanais, 5 mins in a cab, bus or hire car. This has lots of bars, cafes & restaurants should you fancy a change from the AI or want to go out after dinner. It also has tourist type shops. About 25 mins away is Chania, which is much bigger and more sophisticated, with a lovely venician style harbour and lots of winding streets full of shops (leather, clothes, undercover market etc).

Edit: not sure who you are looking to book with, but if it's First Choice, check Eclipse as well as they are often cheaper.
