Some other great suggestions thanks everybody
So I have changed the provisional plan to 5 nights in Bunaken and 7 in Lembeh
Twofish have confirmed that the transfer to Lembeh is in the afternoon so it is possible to do two morning dives in Bunaken and then leave most likely with equipment still dripping water! In any case I think I will leave this card to play at later stage. If I really like it I will do those dives if not i will skip and have a dry days that after 4 days with 4 dives a day maybe is not a bad thing.
I have checked about the night dives in Bunaken and there are some good spots as some of you indicate plus possible mandarin fish dives so I think I will try and have a dusk or night dive each day at Bunaken. In Lembeh it will be 4 dives per day and if I got the mandarin out of the way it will only be night dives.
So right now the total is 38 dives split with 16 in Bunaken and 22 in Lembeh that sounds about right and one dry day in between with other potential 2 morning dives.
There is a saddle discount and I got a quote for 1284 for the whole package accommodation, transfers and 38 dives as described. Value for money is great am sure I will pleased with the budget room and shared toilets!
I also managed to get some flights London to Manado with Sinapore air at the lower possible fare for £652 now I need to find a way to squeeze the equipment and camera gear in 20 Kg plus carry on!
