I agree, pretty sure your boat leaves from P'burg
However Nettle Bay to Grand Case - I would take Love Hotel and Grand Case. The 17th is a Tues, not sure if Harmony night will going by then, if so, it will be busy and maybe noisy - you may or may not like that
However for 2 days, I could stay at Grand Case and not leave, food, beach - it's all there.
Mercure, it wouldn't be my idea of a 2 day stay, I'd rather pick the Sonesta Great Bay over Mercure, to squeeze all the hours before a cruise

However I'd take Love / Grand Case over Mercure. If you'll look at Grand Case, I would also look at any of the Orient Beach hotels for 2 days also.
