Sunbreeze is a good location and a nice hotel.  Their dive shop isn't the
best though, which is a shame.
Hope you have  wonderful time.  I just love it in San Pedro.

So I can't wait to see your trip report.

Robert, here is part of a post I made a year or so ago.

I love the Blue Hole.  It's all in
your perspective.  Last year I did it twice. It is a short deep dive into a
dark hole.  And at depth there are stalactites and a bit of an overhang, if
you are so inclined.  I do not recommend it to new divers, though they take
new divers in there all the time.  I'm against that.

There's sharks in the Blue Hole, very cool, very cool.  It is a different
kind of dive than a reef dive, no doubt.  No pretty fishes, no coral
formations, but think of it.  The geologic history alone.  Amazing.  Check
this out:  http://www.ambergriscaye.com/pages/town/greatbluehole.html

First of all it makes mention of diving to 150', that is incorrect, the dive
is only supposed to be 130'.  And perhaps because I haven't been as deep as
they
mention, I've never seen this extended visibility they discuss either.  I've
never seen a hammerhead in there but ya never know.

For myself, I take down my flashlight and check out the walls, I've found
some little chambers and they've had some little fish in them.  Last time,
when the sharks rose from the depths, I saw one that was swimming parallel
to us.  What a beauty.  So of course, I shone my flashlight all up and down
the length of it.  When it turned and started towards me, I quickly doused
my light and swam off with my group.  But my spidey sense were tingling, so
I looked behind and sure enough . . .there is was coming up from behind me.
I turned and went vertical, it slid by eeeeeevvvvvvveeerrr  sooooooo
sloooowly, just beneath me.  First its snout, its eyes, its dorsal, its tail
fin and then it was gone.   I rose with the rest of the group to make the
extended safety stop just above the rim.  There were a number of fish
swimming around to amuse me while I waited out my time, not to mention the
occasional shark lazily circling our group.  We ascended and I came out of
the water singing "Again, again, I want to do it again!!"  :^)  That was my
5th time in the Hole.

If you do decide to do the Hole, you will probably be on Amigos del Mar's
Pro48.  They break the divers into groups to dive.  Make sure that you get
into the last group to step into the water.  Sometimes the first group
doesn't see any sharks.

The two followup dives are excellent and the surface interval that includes
lunch, is on Halfmoon Caye.  An idyllic little island. Then on the trip
home, if you are so inclined you will be served panty rippers and/or a
Belikin beer or two.  A most excellent way to spend a day.  Sigh.

If you do go, make sure to see as much of this little island as you can.
Scarf down your lunch, head over to the booby bird sanctuary, don't spend a
bunch of time there.  When you go back down to the path that would take you
back to where you started, you will come to a sort of T intersection.  Go
right instead of left.  Watch for the iguanas and hermit crabs.  This path
will take you out to the far side of the island.  If it is not too hot, you
can walk from there back to where you had lunch, and then it's pretty much
time to head out for another dive.  Oh, damn, now I've made myself
'homesick' . . .

Last few times at Maya Princess since it's so convenient to Amigos.  (And
Cholo's bar!)  I like the central location and you can always use Ramon's
beach for swimming.  Also, if you take a cab from the airport, they will pay
the driver.

I find that if you check their rates on the internet so you have an idea of
the going rate, you can usually get a more advantageous rate by emailing or
calling them directly.  Last couple of times I was a walk-in and did quite
well.  (Of course, in the off-season.)
