Pretty much guaranteed extras at most. B2b you would be looking at more independent girls although you might get lucky. PPersonally I would avoid red moon, been twice both poor massage, service and HE. I have read others having a poor experience there lately as well. As mentioned in another post further down one Thai or smile seem to be decent.
Also worth trying would be sexy Sin-Dee do a search on here. I believe she gives a good massage, also FS on offer so will prob do b2b. Might be a bit pricy but she gets good reviews.
