Oh boy, I must be a cheapskate, or put another way, I like MY money in MY pocket....

Room service: I don't ever order room service. I have legs, they appear to be functional and most hotel food I wouldn't feed to my dogs.

Bell service: My #1 rule of travel, if you can't haul it all yourself (no cart allowed), you are travelling with too much ch!t. Any that includes travelling as a family of 4.

Valet Park: I don't ever voluntarily valet park. I am able to park a car myself, I've been doing it for 35 years.... If there is no self park (happened 2x in my life) I will reluctantly valet park and then politely point out when departing that since I was not able to self-park, I consider it a property induced inconvenience and that I will not be tipping for being forced into doing something.

Housekeeping: Nope, not ever. Nether me or my family make any mess at all. I don't tip to do what I would consider the bare minimum (i.e. clean an almost spotless room....)

Spa: Wouldn't know, never done that.

Dining: Yes, 15% max in the US, 0% outside the US. I'm OK with <15% by leaving a written comment on the check as to why I tipped less if food or service merited such feedback.

Concierge: Don't ever recall using a concierge. Not even sure what their function is. I am not a ballet, art studio, loud music gig, opera or fine dining kind of guy so perhaps that's why. The web and Waze is all I need to find a restaurant or directions to a venue.

Barista: Nope, it's a cup-of-joe. But then I don't order a Venti Iced Skinny Hazelnut Macchiato, Sugar-Free Syrup, Extra Shot, Light Ice, No Whip.

Ski Valet: Er, no, never been skiing.
