My friend and I did the self guided trip last winter. We rented their kayaks, stove and water bags.
We shared a water taxi to and from Tobacco Cay. The kayaks were left there for us. Tobacco Cay had limited camping. Some campers we met had their valuables stolen from their tent there. The snorkeling was great at the outside reef. Tobacco Range had an insane amount of mosquitoes and the old campsite was overgrown. Coco Plum was deserted and had no outhouse, but tons of space to set up a camp. We were windbound for 3 nights here. (No snorkeling). Hangman was the best island for camping. The owner was very hospitable and it was a good location to make day trips from. We stayed the other 3 nights here. (Not much snorkeling). Camping possible at Hawkins, but very busy. Great dinners and cold beer! Great snorkeling at Bread and Butter (no camping) and Water Cay.
The best part of our trip were our 5 days at Glovers Atoll resort. The diving & snorkeling were amazing. The island was so beautiful, the food so tasty, the beer so cold….. Good fishing too. The cleaning of the fish is a spectacle! It attracks all kinds of fish, rays and nurse sharks! You can rent kayaks at the resort. http://www.glovers.com.bz
