I have done two trips to Bali in the last two years...love Tulamben!
The first year we stayed at Ocean View Dive and Resort....loved the access to the wreck, menu wasn't very exciting, but lovely grounds, lovely pool and the staff were great.........this year we stayed at Mimpi Resort, again lovely, a little further away from the wreck (a 5 minute drive!), meals were good, staff great.
The reason I went to Tulamben initially was to do a photo class with Mike Veitch at The Underwater Tribe....it was so good I went back this year for an extended trip organised via "the tribe" and will go back again next year. The guides on the last trip were amazing, helpful, knowledgeable, keen and enthusiastic...cannot recommend them highly enough. The thing that impresses me the most about diving with Mike is the fact that he doesn't take a camera so all the attention is on your photos, which can be a bit daunting but the progress is amazing!....all the shots are reviewed and he makes suggestions via the "magic slate" so you get instant feedback and recognise what to look for and what to do....
No doubt you will enjoy your trip, best of luck and have fun.
