nycdive:I would be alright with $140 for that many destinations and less of a headache. I really wish I could pare this down to two stops that were a good base for these places, but the likely contenders don't seem as appealing to me. Lovina sounds like it would be a reasonable place to get to Menjangan and Tulamben from, but I keep hearing that the hawkers there are near unbearable. Also, how realistic is it really to dive Tulamben from Lovina? Should any of these locations I've mentioned be given more or less time in your opinion in terms of the dives being worth it? Again, thank you for all the help.
Tulamben is one hour plus drive from Lovina - I think Tulamben deserves at least 2 days diving do you would be better of basing yourself in Tulamben area - Given the choice I would spend a few days in Tulamben, a few days in Candidasa.
Also note that close to Lovina there is a great muck site with very good chance to see mimic octopus - Can't remember the name now but if you do a search you should find it quite easily.
Anyway whatever you decide you will a great time - Bali is a beautiful place with plenty of amazing diving.
