Things to do in CocoCay(8am - 4pm)

We aren't really into adventure-type activities(think parasailing, swimming with dolphins etc). Are there any low-key activities or is it just "have a nice beach" day?

Also, with Royal Caribbean - is there an on-site lunch or do we head back to the ship for lunch?

You can just make it a nice beach day.

You can walk around. There is some shopping. There will be a lunch.

They do have water-activities, for a fee. You can book them in advance, or simply wait and see if you want to do it once you're there. Things like wave runners are a "follow the leader" tour...you can't just rent them and do your own thing.

Do they rent stand up paddle boards or kayaks by the hour? ... and how much it might cost?

They have a bbq lunch--ribs, chicken, hot dogs, hamburgers, fruit and some things like that. No need to go back to the ship. You'll have to take a "tender" over to CocoCay, so it's kind of a hassle to go back and forth. You'll want to bring everything with you.

I like to rent a beach lounger. They are located on the quieter side and have a bar right next to them--plus you have shade.

You can rent kayaks, but I think you have to do a guided tour--I'm not 100% sure on that. You may be able to rent them by the hour.

I love Coco Cay as a quiet beach day.

When I was there with our group of 10 in November of 2016, some of us rented snorkel equipment for pretty cheap (I can't remember the price, it was definitely under $20, and maybe under $10). There are a series of "shipwrecks" and sunken small airplanes dotted all through the cove, some closer and some further away, and interspersed with docks you can rest on. We had a ton of fun moving from spot to spot, looking at the sea life. I would wait to book anything until you are there though; we almost didn't make it to the island because the seas were so choppy in the morning. We were below decks waiting in that line FOREVER. Still, I guess we were one of the lucky ones because I hear a lot of people don't get to disembark there at all.
