As soon as I decided to visit Flores, I started my research on Internet about the best cruise I could afford.
I contacted basically all the best reviewed in Trip Advisor and then I decided to do with a local, Indonesian Boat and tour, in Tripadvisor the best of the local ones.
Even if the price was not so cheap in comparison with others (7.000.000 IDR for 2 days for 2 person with AC), as the picture of the boat was the best in compare of what the other locals sent me, I confirmed everything at the end of January and reconfirmed again 2 weeks and 1 week before my arrival.
Yanto, this is the name of the owner of Indonesia Boat and Tour, the day before our departure, at 19:00 (!!!) send me a text, saying that due to reorganization of the boats I would have another one, but with the same specification… I asked for the picture and… It was not the same as discussed…
The manager of Wae Molas (Rajab Halla) helped me to find a boat directly at the harbor and I decided to do 2 days with 2 different Boat, without overnight.
The cost per day was 1.300.000 IDR, the boat clean and the tour, both of the day really amazing…
Just after my experience these are my recommendation:
1. Do not use Indonesian Boat od Yanto and for sure do not send money in advance!
2. If you want to book in advance, do it, but with Wunderplus. It would cost 15.000.000 IDR for a private tour for 2 person on the Mimic all included. The boat is really good, safe and clean. European standard
3. Snorkeling equipment could be rent in the shops close to the harbor for 15.000 IDR. I do suggest to come with your own mask and to rent just only the fins.
4. I do suggest to arrive in Labuan Bajo and to go directly on the harbor and find a deal with a local person, better if you would be with some person of your hotel (Rajab of Wae Molas was really a great help!). The price, food included should be around 4.000.000 IDR for the 2 days for the complete boat for 2 person. No A/C.
a. Be aware that the engine is the most important part of the boat. The sea is really dangerous around there and would be better to have 2 in good condition
b. The toilette: this is the second important thing. Please check it, not only if proper, but only if it works
c. Bed and overall cleanness
And remember, HAVE FUN!
wherever traveler 
Great recommendations!
