I'd like to add something here too knowing some stuff about Grand Cayman.
April by the way could be one of the best times for sting ray city ... bad winter wether (not that bad .. but bad for here) is over and there is no real algae bloom yet so the water isnt that green ever until like july.
September is still my fave time of year for conditions as long as a hurricane doesnt come through.
Grand Cayman is not that expensive especially if you think about your vacation. Accomodation and diving can be cheap especially with packages.
A month like spetember is almost dead tourist wise for some unknown reason, so you can get better deals and better weather and less packed dive boats.
there are SOOOOO MANY dive operators who specialise in photography.
and Camera Equipment is Duty Free !!!
You have more choice than most places I have ever dived in different sorts of dives
and if you are a photographer who either knows what to look for in the northern caribbean or you actually take your eye out from the viewfinder you will find much more than has become stereotypically expected in Cayman
when I dive with Alex I think I am safe in assuming we both learn something new about the area and we have both been diving here for many many years.
If you have never dived Grand Cayman then you should, theres a reason it is a mecca for diving and always gets in the top 5 lists (even if the rodales boys do get freebies here a lot!)
It's easy yet dramatic, technical yet safe, busy yet quiet.
Very rarely will you find over filled dive sites, theres too many !!!
Every dive is different even at the same site, everyone has their favourites.
And the dive companys may be busy but theres loads to choose from depending on what you want.
Come to Cayman ... if you do .. you will come back .. everyone does ... it should be the Cayman Slogan .. its what all the residents of cayman say.
