I've stayed in a couple of hotels that had bellboys, but the vast majority of the ones I use don't have them. I don't mind too much - its one less person to have to tip *g* (I don't mean that in a bad way, I will tip them if I have one help me, but I can't really afford it).
The one thing I hate is when the lifts are broken, and the hotel doesn't have anyone to help with bags. I was in London once on the way to a flight, it was roasting, and I was ill with heat stroke. The lifts were off, and I had had a bag on my shoulders and another bag wheeled behind me. I was obviously struggling, to get them up the stairs - then I found that the key to the room didn't work - I had to lug everything back down again, then back up with a new key - and they never once asked if I needed a hand.
Gotta love 'customer service'.
