Sorry I haven't answered your last post until now- I just found it tonite. I'm sure by now your Keys trip has come and gone, as has mine, but to get back to the WPB question, we prefer WPB for several reasons: 1) It is deep enough to get out of the surge. Most dives in the Keys are shallow, around 30 ft or less, so if you have rough seas on the surface you are still getting moved back and forth by the surge even when underwater. WPB average diving is probably in the 55-65 ft range. (even deeper at Juno sites or on most of the wrecks) so you are deep enough to have whats going on topside not bother you at depth. 2)A big variety of big critters hang out there, including turtles (some in the hundreds of pounds), several varieties of sharks (we had a 16+ ft Great Hammerhead hanging around on our last trip), MANY Goliath Grouper,huge Barracuda and big fat Morays. 3)Schooling fish so numerous at times they totally engulf divers. 4)Generally better visibility (a bad day is 25-40 ft) 5) IMO a healthier reef in general (Gulf Stream coming in close to reefs=more nutrients). 6)Shore diving is possible. Diving under the Blue Heron bridge is FREE and if you like critters they are there! ALL kinds of juvenile critters along with invertebrates and just about anything else you can think of has at one point (seemingly)called the pilings of the bridge "home". Just have to check the tides and go at the right time. 6) Hotels are about 40-50% less than in Keys. We Priceline a room at the Marriott or Doubletree in Palm Beach Gardens for about $40 a night. 7) If it's really ugly out there is more to do ie:shopping/restaurants/movies. One thing you need to know is that all diving (except shore) is drift diving. (It's that Gulf Stream influence again.) Sometimes it's almost non-existent, but sometimes it's ripping.
We actually went to the Keys last month (July) and left there half-way through our week to go to WPB because the seas were too rough,surge was too bad, and viz was only 20ft. Hope you get the chance to dive WPB!
