As to how much to allow for tips...man, my tipping budget is huge LOL. I've just known too many people in tipped positions to stiff them.
Not including meals, I plan to tip:
Towncar driver; 15 dollars each way to/from airport
Mousekeeping; 5-10 dollars per day for 3 people in the room (10 would be if we had turndown service). If 4 people in the room, I tip the regular mousekeepers 10 per day and tip another 5 for turndown. We use a LOT of towels.
Bellmen: $2 per bag usually, sometimes more if they're extra helpful (or like the one at GF last year who took the time to fill our icebucket for us before he said goodbye! In any event I never tip a bellman less than 10 dollars.
I would also tip a couple dollars extra for getting extra blankets/towels brought up.
We don't have many skycaps at our local airport, but if one approaches/helps us in Orlando or elsewhere, we certainly do tip them and well! I have only had a bag lost once in my life, and that was when my *cough*cheap*cough* ex husband wouldn't tip the skycap. They sent our bags to Dollywood instead of Disneyworld!
Man, I better start writing my list down it's adding up. But I couldn't enjoy my trip as much if I didn't take care of the people who were making my stay so magical. It's more fun to share

For a week long WDW vacation at a deluxe resort, I'm figuring we'll tip about 130.00 not including food related tips.
Safetymom are you having/did you have fun at DL? After all that weather in FL you deserved a perfect trip!
I'm so glad they're listing mousekeepers at DL as a tipped position now. They work hard, they deserve tips. I have a relative who worked in housekeeping at a hotel (not wdw) and it's backbreaking work, and heaven knows they're underpaid. Hopefully WDW isn't far behind.
