I booked with Orbitz for our March Cancun vacation. We're staying at the Flamingo. I received a voucher for a "free sunset cruise" with grayline. Has anyone done this before? I read on trip advisor from 1 person that it actually was kind of fun. I guess it's a marketing tool to advertise their excursions. I'm interested to hear from anyone if they've done this before, if food/drinks were included, and anything else you'd like to share. Also, on a related note, the booking info says we get a "free dinner at Sr. Frogs..." Does anyone know what this is about?
