Driver already knows who you are and where you're going. S/he telephones the hotel just before you get there, and staff is typically awaiting your arrival at the front door. IMO this just enhances the luxury experience of staying at a top place like this. When I arrive at BKK, I always use my hotel's car service if I anticipate that there's a possibility that I may be stressed. After I've been flying for 25 or 30 hours, I want arrival to be as easy and mindless as possible.

And, yes, I've used the hotel car service even on a short flight like arrival from HKT. A couple of kids, a number of bags, easy for a minor burp to escalate. I love having someone waiting for me holding a sign with my name on it as I exit bag claim. Then I know that I can relax, stop thinking, and everything will be taken care of properly. Only you can decide what that's worth to you. For reference, my hotel charges closer to USD $65 for this.
