Good morning to all seniors and all.
I am planning to visit visit bangkok in 2 months time with a group of 5 guys (including me is6).
We are planning to visit Big Apple but only found limited information and would like to seek help to our questions as stated below:
a. We are gng for membership as i think it is cheaper at G club and most prpbably looking at the 10K baht membership which comes with a few bottles.the qn is are there food served in big apple and if yes, is it expensive?
Yes, food are serve at the outside area & price are ok.
b. the salesperson for the membership is to take care of us? Does it mean that he/she will arrange to have a gal each for my group? I understand that we have to pay each gal like 300 baht for 45 mins "companionship" time. Will the gal stay with the guy throught or ?
Most likely will be the mms arranging gal and membership for you, gal will stay until u leave and per 45min charge apply.
c. Is there vip room that we can have? Any rates?
If not wrong there's 1 or 2 room but is outside of the hall/stage area, can try to call them and ask for room price and make early reservation.
d. Any dress code for G club?
Nope, just how u like to dress to impress the gals there.
e. any advice are welcome.
Additional advice is try not to give lady drinks if they ever ask for it, just drink from your bottle will do, give tips to waiter 100 baht each and not forgetting to tip mms or the gal although is not necessary like most Thai people don't tip.
We are also thinking of renting a minivan to ferry us from airport to our hotel and also to bring us around bangkok. We are also looking for a english speaking driver for this minvan if possible. Most probably we will need this driver to pick us up after our drinking sessions. Is there any recommedation to get such transport?
Usually van booking from 8am-8pm (12 hours) and additional hour consider overtime charge, not really advice to book van to move around in bkk due to bad traffic. travel by mrt/bts will be easier if you can get hotel near any station. As for transport at night after drink, guess getting 2 taxi to/from big apple will be easier.
Lastly, it is one the guy's birthday during thr trip and we intent to break his virginity and would need recommendation for a good place to celebrate and end up him having bonking.
Try to book room in massage, there's some with 3bedroom suit etc with jacuzzi, so u can book gals for 2 session, hv some karaoke, drink, naked jacuzzi party and bonk in the 3/4 bedrooms provided. 
Thank you for your time for reading and recommedations.
