I purchased two vouchers for a San Francisco Bay tour. When I tried to use them the company said they didn't know who Townhog was and I would have to deal with them. After days of leaving several messages and emails I finally received an email response that they were sorry that I could not use the "full value" of the voucher and that they may be willing to send me a credit for another voucher. Why would I want another useless voucher. I'm from out of town anyway so it's too late. Stay away from Townhog. It is a rip off and you will be taken just like I did.
