just a note on canceling your membership...do it in writing rather than by phone. If you read the FAQ you can cancel either way. Send your cancellation with at a minimum delivery confirmation or even better by certified mail and you have PROOF of when they received it! According to my credit card company, they almost never have problems with continued charges for membership stuff (this or any company) if the cancellation is in writing, it's the phone calls that cause problems b/c then it's more of a your word against theirs thing.
I just cancelled Connections after buying the vouchers we needed so I happen to have their address here but you can get Hotwire or Simple Escapes or any others (all run by the same company) from the "contact us" link.
Connections is:
