Quoting from your initial post, "Life is good when you have to make decisions like this...," I hope that you sincerely mean it as a glance at your activity on this Coz trip to date---->
http://www.scubaboard.com/search.ph...d=147404&sortby=lastpost&sortorder=descending could leave one with the impression that it's shading over into obsessional worry. This surely would be a shame, as pleasant anticipation is such a big part of the fun of a dive vacation.
Coz is a not to worry dive trip. It's been a dedicated dive destination for over 20 years, accommodates over 3/4 million dives a year, has over 65 dive ops that are safe, professional, have the gear you need & will show you a good time u/w, and is populated by friendly folk who want you to enjoy yourself.
See here, Old Pippin, if you can't unlax over a Coz vacation you're never going to survive planning for Papua New Guinea, Wakatobi in the Tukang Besis or the Komodo Islands somewhere down the road.
Also, I'm a bit confused as yesterday you stated, "I will have the middle of March thru April off and want to plan a trip to coz (10 days?). I would like to avoid the worst part of the spring bread rush, what is my best bet during March/April?," and today you indicate, "It looks like we'll be there in the middle of the spring break (probably 2nd and 3rd weeks of March)."
In any event, as you obviously know it's not going to be as quiet as if you went early March or late April. However, it's not going to be intolerable, either. Look on the bright side---at least you'll be missing Carnival 2/26/03-3/4/03.
Here's what I suggest that you do: (1) Rent your vehicle early, as if you wait until you arrive there well could be just junk left; (2) Dive with an op that offers six packs or other smaller boats, like the already discussed Dive Paradise EDP or Belinda with Aqua-Safari; (3) Avoid centers where the spring breakers drink, mingle & party, like Carlos & Charlies, Kiss My Cactus, the plaza, etc. This is easy to do; (4) Eat at off the main drag places, of which there are scads.
Trust me on this one, sharkman101, you're gonna have a fab time.
Best regards.
