I got me a toll-free number for my bike ride (to make it easier e.g. for potential hosts to return messages). The number I got differed by one digit from the internal tech support number for Wyndham Resorts (and a repeated digit at that--in one case it was the same as the digit before, and in the other case the digit after).

Anyhow, just thought you might want the advice to avoid getting too attached to a particular toll free number until you've seen what sort of misdial/collision situation it has.
