We stayed here.
The price included a song thaew pick up from chantaburi bus station and speed boat to the resort.
All food was included...you had to have a serious love of squid and crab, as we do.
A week would probably be too long though...3-4 days ideal.
A snorkelling trip was included.
Looking at the website pics it doesn't seem to have changed much.
