The Royal Cancun... Trust me, this is the same resort that we literally had screaming matches with because they told us they refused to book room blocks and that "nobody does that". Are they nuts?!?! EVERYONE does that and if we are bringing 100 people (yes, that many!) to their resort, they better damn well accomodate everyone!!!
Whatever, we love the resort so much and overall our wedding coordinator there is amazing so if that is the only bump in the road, we will take it. It is just annoying not to have 100% piece of mind knowing it is booked for that date.
