Bio Bay on a Sunday?

In order to get better flight prices we added a night pre-cruise and a night post-cruise. We'll be there on a Saturday in the evening (full moon) and the following Sunday (marked "best" for viewing).

I would love to see this. It's a bucket list item for me and I don't know when I would get back. I can find tours on Saturday, risking poor visibility, but I'm having a really hard time finding anything on Sunday, most places are closed.

Do you know a tour that runs on Sunday?

Would going on a full moon be probably ok?

As a side note I am going with my DH and three boys, 11, 10, and 8. I was thinking a small boat would be better than kayaking.

You must be looking at January or May 2016?

Most companies that operate in the Fajardo biobay opted to not run tours on Sunday night (their licenses only allow them to operate for 6 nights/week). There is one kayaking company, and one electric boat company, that operates on Sunday nights. This Google search should help you find those ... http://lmgtfy.com/?q=laguna+grande+fajardo+sunday+nights

(cruisecritic rules prohibit locals like me from mentioning companies by name).
