Wanted to chime in on diving the day of arrival. I am not sure on the other shops but Aldora guarentees a dive the day of arrival, unless of course you arrive so late in the day it is virtually impossible, i.e. late afternoon or evening. I have never heard them say it requires x amount of divers. There are no doubt numerous excellent dive shops, Aldora is who I dive with because of the comfort factor. I fall into the category of creature of habit. One of these trips I want to do a day of diving with Christi's shop because of the glowing reports from the divers. BTW scubabum2, I saw airfare this weekend from DFW for $99 round trip. We are going down for Fri-Mon to get a fix. Still counting $ for the ladies in pink?
