Hi! Thanks all for your suggestions - there was a crazy special deal from explorer ventures in the turks and caicos that i ended up going with! A little on the earlier side (early November) but the water should be warmer too...am very excited! Although that citizen science trip looks awesome, I literally booked several hours before seeing that...next time!!!
That's terrific! We did the T&C Aggressor trip a couple of years ago during the first week of November and the water temps were 82-84 so it was really nice diving. Beautiful walls and lots of healthy sea life, sharks and other critters.
I hope you will have a some time to enjoy Provo, it's a great destination! Just a word of advice, the airport is packed on Saturdays so avoid it if that is a possibility.
