My wife & I are spending 5 weeks on Cozumel,last week of Dec. & all of Jan. Needless to say just condo. & food alone will be expensive. Then comes the most important part of the vacation THE DIVING!!We have contacted numerous dive opps most of whom do not want to give discounts for multiple dives (between the 2 of us approx. 50 X 2 tank dives ) Caballito Del Caribe have given us good prices, stowing our gear, small fast boats etc. but we can't find any reports either good or bad! Please can anyone help with any info.?
