first time snorkeling

hello. I am getting married soon and we were thinking of a cruise for
the honeymoon. I hear there are some fun snorkeling stops. Which areas
would you suggest? I'm not a great swimmer but do ok and my wife
doesn't swim at all but still wants to try.

I think we both would feel better if she just kept a vest on the whole
time. She is still a little nervous though. What kind of vest would you
suggest here for snorkeling? I will probably get the vest locally so
she can try it on.

For myself I will really need some corrective lenses. What is the best
website to buy the ones with inserts? I believe our local scuba shop is
very over priced. I was also wanting to buy swimming goggles and not
sure if they made them with the inserts also. I would probably bring
along one of the inflatable vests for myself in case I get adventurous
and want to dive down.
