Generally speaking...
1. Bell Services gets about $1 per bag
2. If I ride DME and feel that my driver gave exceptionally good service, I tip $2-3.
3. At restaurants, I tip at about 20%. If the service is subpar, I tip less and mention why to a manager if there is one in the area.
4. Housekeeping is a subject of great debate. Some like to leave $1 pp each night. Disney tells us that housekeepers are not a tipped position....but many guests just want to leave something.
5.Valet gets about $3 or so each time I interact with them.
I can't think of anyplace else that would normally mandate tipping. Anyone else??
