Questions about Cruise in January to Southern Carrieban / Barbados etc

Hello group

I am going on my first ever trip outside Europe, to the carribean on a
cruise. We will fly to Barbados then board the ship and visit a different
island most days. I have a couple of questions for anyone who can help:

1) I suffer from IBS, and often get random attacks where I may suddenly need
a toilet. What are the islands toilet facilities like, are there public
toilets at most beaches and tourist locations and in the port towns? Are
there public bars and hotels that would allow use of toilet facilities in
urgent situation!?
2) What is the temperature like in January in that area of the world?
3) Will we be pestered by insects, flys and wasps whilst off the ship?
4) Any good websites where we can plan ahead for each of the islands and go
to see the best places of each island?

thanks

That's the best period to go there, i.e. the driest

There shouldn't be insects at sea. Watch out for the mosquitoes on land.

Have fun.
