Koh Samui Info. Please

Will be on Koh Samui for 3 weeks later this month. In order to make our trip more enjoyable, can anyone advise about the following:

(1) babysitting services

(2) fitness centers / weight rooms

Will be staying at Lamai Beach so that area would be most important for us.

Thanks...

Pick a hotel which has these.
