Going through the parking garage is not an option. In the evenings the lobby is rarely very busy (most of the action is in the bar/restaurant to the right of the lobby). The elevators are located BEFORE you reach the check-in area.
If you go to the check-in desks they will ask, and if a girl arrives unaccompanied she will have to leave her ID before they will send her up in the elevator, but if you come in and walk straight to the elevators, they might not even see you. I skip the desk when I'm with a girl I know well from one of the bars. If with a freelancer I use the desk.

No need you can take the elevator without going via garage anyway not possible as parking is on higher floors

It gets mixed reviews on these boards. I like the place but I can fully understand the people who say the don't. The rooms are very good now as a lot have been refurbished. It is geared up for guests as there is a separate desk by the lifts for the guest to show ID etc, this is more convenient and discrete than going to reception. No charges for guests, I suspect if they tried the hotel would empty. It should be fine for your needs.

Some like Dynasty Grande it is over 20 years of age but most is over 21. Sensible either way as you don’t want to be caught with a minor. Taking ID’s at reception seems a sensible precaution. Not only because for some LB’s it’s impossible to tell their age, but the phone call from reception to your room in the morning asking is everything OK before they hand back the ID is an added security.
Funny, I’ve stayed recently for three weeks at both the Landmark and the Mercure on Soi 11 and never once was my companion for the night asked to show her ID. You would think for that standard of hotel it would be compulsory. Maybe they don’t want the girls around the reception at check out time. They want the guests business, but turn a blind eye to their activities.

I think Knobby may be referring to these guys, Bangkok Airport Limousine. 1250 baht for fast track service alone, 1090 baht if you book car service along with fast track. I used them on my very first ladyboy trip years ago because I didn't want to be standing in a long immigration line while badly jet lagged. I haven't had need for them since, but it all went off without a hitch when I used them. It was very efficient and fast. They are not a dodgy outfit, they've been around a long time. Their car service was solid also. Spotless cars driven by sane drivers with good English skills.
