Well, I'll buck the trend and say that I really quite like the welcome, dancing, drumming and flower garland if - and ONLY if - the ceremony is:
1. short
2. doesn't involve my participation in any way - including any kind of conversation about my flight, my plans, the weather or the hotel
What I really loathe is the phone call 20 minutes after check-in to find out if everything's ok. To be polite, after a long flight the one thing I'm really looking forward to is some private time in the bathroom (hence the need for the welcome to be short) and I'm not in any position to be answering the phone. Just leave me in peace!
