As a provider, the holiday season is a time where I see a few less appointment requests. People are traveling a lot, trying to keep up with work, spending time with family and friends at holiday parties and the like. If they have kids, the kids will be home from school and/or trying to get through finals and such.  

Incidentally, I see more requests for couples appointments during this time of year- as a chance for both partners to unwrap a gift that keeps on giving  
My availability is also reduced because of graduate school demands and the cost of incall is a lot more more because hotel room rates shoot up.  

If you want to do some traveling, perhaps use a mailing list of your clients to see who is looking to spend time with you. And do tons of advertising. It may be worth it, may not.

traveling on Christmas... a week / end of year yoga retreat to back super refreshed!
