The Pink Tulip guys sold up and moved to Hoi An. They reopened there, but I haven't heard any reviews of the new place yet.

I broadly concur with what other people have said ITT. I've heard that some people have difficulty bringing a friend back to their hotels in SGN, but I have to confess, I've been there 7-8 times over the years, and never had a problem.

Just find a hotel that has good reviews, but looks ever so slightly sleazy (maybe has a massage parlour attached, or just has shag palace decor). Be really nice to the night porter, give him tips on the form of beer, or whatever, as a token of your appreciation. Be discrete about your sleaze, so the hotel can retain a veneer of being a wholesome, family oriented establishment, even if it's anything but. These are the guidelines I follow, and they haven't failed me (yet).
