Spent the last weekend in Bangkok and had a pretty good time at Alaina. First time there and it was really quite eye-opening for me. The place is doing well with alot of girls to choose from, and because it was a pretty big group of friends who went together, there were 6 of us who each chose a girl. There were 6 categories:
A - 1900bht
B - 2200bht
V - 2600bht
S - 2900bht
M - 3500bht
L - 3900bht
The ranking system is quite funny, but a running joke among my friends was the V-ranked girls represented value, cos they were decently cute and 2 of my friends who took from this category were quite satisfied.
As there were 6 of us, we were given a huge VIP room, with a huge snooker table and a jacuzzi which can comfortably sit 12 people. That was the highlight for me cos all of us were just soaking and enjoying our girls in the huge tub, like a scene out of those black triads movie.

After about 10 minutes in the jacuzzi, then each of us break out into individual small rooms with our girls, for our respective happy time. I took an M girl who was quite a looker and very hardworking, but quite a piano massage. Otherwise it was pretty fun and worth the 3500bht for 1.5 hours.
I would say Alaina is very good for a large group of brothers/close kakis to go together, as the VIP room and huge jacuzzi tub was a really nice bonus. On top of the all-in price based on the category you choose, you just need to top up 300bht more for a drink of your choice and a lady-drink. Total damage = choice of girl + 300bht (3800bht in my case).
Highly recommended and looking forward to going back again in the future.
