We were there in mid-Jan of 2004. Pouring rain when we arrived and cloudy for a couple of days. Then sunny and hot!
Try to get a room on the second floor (they seemed to be nicer and quieter). Our main level room (and a few others) had some bad smells and we used Lysol to help get rid of it. The bugs were not bad at all - we used some repellant, but sometimes forgot - didn't get one bite.
Food was so-so and not a lot of variety. A number of us got some sort of stomach illness that lasted, at most, 24 hours.
Dive marina was great - liked the showers (near the dock), the gear storage area was OK, but could use a bit of freshening up. The boats are easy to move around on and lots of room to get gear on and off (guess it depends on how many on at the time - we usually had 10-12 divers.) Dive guides/masters were helpful and friendly.
All the dive sites were really good and we enjoyed them all! Never had any time limitations or restrictions. Nitrox is available, ($7 per tank or $100 for all week), and the fills were always good (about 3200 psi). Diving off the gazebo (to the plane and Prince Albert and wall) is a lot of fun. Best night dive I've had at a site called Missing Link (out of the few down south I've gone on.) Be careful and ask if there are Sea Wasps around we never had them, but the other boat (on the same site and night) did.
Docs Wall was really nice. There is a chimney to go through, we didnt do it and cruised the wall. The people that did, said that they only saw bubbles from the divers below them.
Marys Place was OK, but we had a bit of current and the vis wasnt great.
We did the snorkel encounter with the Dolphins at Anthonys Key Resort we enjoyed it!
We also did the shark dive (Waihuka Diving). It was 3 miles offshore and at 70 fsw. There were about 15 Reef Sharks and lasted for 35 minutes. It was exciting being around and near (had to duck once) large sharks. The current was strong from 40 feet and up, but calm on the bottom.
Water temp varied between 78.8 - 80.2 Saw lots of critters: octopi, squid, sharks, turtles, rays, queen angel, drum, seahorses, eels (saw some babies on the wall at Doc's Wall), and lots more. The coral appeared to be fairly healthy and interesting.
We only experienced a bit of surge on one dive and the seas were fairly calm all week. All in all it was a great week and I hope you guys enjoy it as much as we did.
