We agree that JW Marriott Phuket is great. There are a lot of complimentary organized activities for children aged 4 and above. You can drop them off at the Kids Club as long as you're at the hotel (at the pool, gym, spa, restaurants, etc.) For kids younger than that, you will have to pay for a baby-sitter though. It's THB200 or appoximately HK$40 per hour (as of February 2006). Hotel's foods at ANY of the restaurants are awesome and very reasonably priced.
