Thanks John. Juggling so many things, I think we're too late for anything but keeping our points reservations at the Marriott. It means running through hallways with wet dive gear and getting dirty looks but hey. It'll be worth it!
We also have a car, and I think I will indeed try various spots. The spots near the marriott seem to want to give you 'guided beach dives' and don't just rent tanks. Might take one or two for an orientation (and help the economy) but .... would be nice to take our time with tanks on our own.
@JohnN If you have great sites (esp for Macro) to suggest, I'd appreciate it.
Thank you
Jaan
