Excursion wise this is what we are thinking:
Grand Cayman: Fat Fish Adventures jet ski, stingray city and snorkel (I am a little bit nervous about this but I am going to be a big girl and try it out lol....who knows maybe I will love it.)
Costa Maya: A relaxing day at Maya Chan
Cozumel: just walk around the port check it out, then head back to the quiet ship ride the aquaduck and spend the day in the rainforest spa.
Castaway Cay: explore the island and have a beach day.
What are you guys planning for excursions?
For us, we're thinking about Stingray and Beach Combo for Grand Cayman. For Costa Maya, not 100% sure due to the pretty short time available and it will be my 40th birthday on the day so I'd like the day to be special. For Cozumel, quite a few options but undecided yet and might as well enjoy the boat. For Castaway Cay, my partner wants to try Parasailing as he was booked this January but the weather prevented him to enjoy it.
