I think it's reasonable to ask at reception to be moved if this is the case
Absolutely.

UASPG, can you recommend any highlights outside the hotel to do on Koh Samui? I've read about Ocean Beach Club.
Are you referring to the Beach Republic on Lamai?

It really depends of what you like. Quiet and nice places, party scene, animals, local culture, beach, shopping, etc ....?
Let me know and I will try to help you the best that I can.

PS: if you wish, PM your email address and I will send you some pictures of the hotel.
