We've always had great experiences with Travelzoo in the past. Traveling to Costa Rica with vouchers twice, using vouchers for weekends around California. I recently purchased a voucher for a hotel in Mexico. I tried emailing the hotel to book my trip, as instructed in the Travelzoo voucher. The hotel has never responded. I changed my preferred travel dates and emailed again, no answer. I contacted Travelzoo for help and they indicated the hotel replied to them and that I just needed to try different dates, but the hotel still didn't reply to my emails. I asked Travelzoo for a refund, since clearly something is wrong and Travelzoo is not backing up their service. I can't, in good conscience, purchase from Travelzoo again. And, am uncomfortable continuing to "harass" the small property with additional emails. How many emails is too much? Bad business Travelzoo. How can you not stand by your business, when the travel partner doesn't honor the vouchers?
