Groupon Getaways - your experience?

My boyfriend and I are looking to plan a trip and the deals I see on Groupon for places like Costa Rica, Dominican Republic, Mexico and so on are great! I notice most of them are through Travel by Jen. I’m wondering if anyone has purchased a package through Groupon and what the experience was like? Was it hard to book the flight, travel from the airport, were the accommodations not as promised, etc? Thanks!
