Thanx, guys!
Cebudiver, you are right, hiring private boat for 6-7 people will not be cost-effective in comparison with regular boats.
Lars, I already got info from Sea Explorers and discussed it with my friends. We decide to do self-made trip
Also, I spend several hours analyzing airlines schedules and made optimal connections
Here is it:
1. Fly from Russia to Kuala Lumpur, overnight
2. Fly from Kuala Lumpur to Manila. City tour, overnigh
3. Fly to Cebu. Trip on Visayas (Cebu-Moalboal-Dumaguete-Siquijor-Bohol/Panglao-Cebu)
4. Direct fly from Cebu to Bangkok
5. 2 days in Bangkok, then fly home.
About Dauin/Dumaguete instead Moalboal. It is possible to arrange diving around Pescador from Dauin/Dumaguete? In this case, we can fly from Manila directly to Dumaguete instead of Cebu.
Oh, of course I carefully read Dumagueteinfo and other web-sites about Visayas and know, that only way from Siquijor to Bohol (Tagbilaran) is via Dumaguete. But thanks you for pointing my attention on this fact
