We have an amazing Wedding Coordinator/Travel Agent, Linda Cole,  that is helping us get everyone to Cancun. We are staying at a luxury all-inclusive resort, and Linda has negotiated an amazing group deal for us.  Please click on the link below to see information on resort and pricing. She can add/adjust days, upgrade rooms, and help arrange flights.  She will also price-match anything you find online.

Just an FYI, there's a chance you might find a packaged deal cheaper on one of the travel websites. However, if the resort sells out, the people they would move to another resort, will be those that didn't book within the group. There is also a daily fee of $100 per person per day for a guest pass if you don't stay at the resort. (Apparently, every resort does this.) In my opinion, all of the leg work has been done by our wedding coordinator, so it's easier for you. 

Having said all of that, please stay where you will have the best experience. We know this is a financial committment for you and your family, and we want it to be amazing for everyone.
