last year I have been in "Divers Lodge Lembeh" : ( easy to find with google...I don´t know if it is allowed to post the Link)
They do have a smal house reef, but it is for shure not the best Place in Lembeh - but Ok for a night dive.
The Resort ist lokated in the Lembeh Strait.
From Divers Lodge Lembeh you will not be in such a big group on a Boat.
I have been on a Boat with two of my friends and we had two guides !!
Those guides do now there dive sites, they will show you a lot of rare critters. But it is not a Zoo, nowbody can guarantee to find the yellow striped, hary pygmae Seehorse
They are used to handle cameras !
The food is very good, I got a few more kilos on top
You don´t need cash there in the Resort. ( Just give your Purse to the owner, he will store it in a Safe for you )
I did not close my Room there, there is no need to do so !!
The trasfer depends on the Critter you want to see and where it shoud be !
So the Boat ride can be 30 Minutes ore around 60 Minutes to the dive Site.
