Hello!
We have a package through Sunwing, and none of our guests have been able to find a better price than our group rate, although many have tried!
We've had a few guests book their own flights, only to avoid travelling on Sunwing, which has a terrible reputation for travel delays. I actually know a few pilots and flight attendants who work for Sunwing and they are apparently very understaffed and pretty much always have delays.
So some of our guests book Westjet flights to avoid the Sunwing problems, but they are spending a lot more to stay at the resort.
I was actually hoping to avoid using Sunwing, but the prices were so much better that in the end we decided to go with the lower price and cross our fingers it all works out!
