We took the submarine tour in Georgetown about a year ago. It was a neat little tour.
The Atlantis tour office is immediately to the right as you come off the pier where the tenders drop you at Georgetown.
They use a small boat, about the size of a tender, to ferry the passangers out to the reef area, a 10 or 15 minute trip. At the reef, you watch the previous trip surfacing. The submarine has large portholes along both sides and one bench along each side. Everybody has a window seat. In addition, the front of the submarine is all glass. You dive about 90 feet to the reef and the sub tours the reef for 50 minutes or so. Schools of fish, coral growth, a small shipwreck. Back to the surface, back on the tender and then watch the next trip submerge.
I can't remember the exact cost of the trip, but do know that Celebrity marked up the Atlantis price by 20% if you buy it in advance onboard the cruise ship. Atlantis has a toll-free number 1-800-887-8571. I suspect they also have a website but don't know the address. The trips go every 1-1/2 hours so it shouldn't be any problem making a last-minute reservation.
Just one suggestion on what not to do on the tender. Do not sit your camera on the bench with the open back. A couple asked me to take their picture. They handed me their camera and I set mine down on the bench. After the picture was snapped, my camera was gone. It had slid off the bench and then fallen overboard from the upper deck since there was no kickrail around the deck. Goodbye $50.00 worth of camera. Luckily, I had just reloaded the camera and lost no pictures. In addition, another couple from our ship loaned us a disposable camera til we got back to shore and I was able to buy them a replacement. If you take the tour, be one the lookout for a small 35mm camera. Maybe, the sub captain will stop to let you retrieve it for me. ;>o
Speaking of picture taking, they advise you to not use flash and use ASA400 film when taking pictures through the porthole. Unless you have a camera that provides automatic exposure without flash, you will be disappointed with the results if the object is more than five feet from the submarine.
