That is way too many free rooms the hotel will have to provide for the number of paying customers who will actually show. I imagine it is at least two to a room, but how many people pay for this event?
Check out the SHITTY quality of the youtube version of that commercial on their site.
"For four days and three nights, the Hilton Rose Hall Resort in Montego Bay will be home to the greatest Ronnie Mund Block Party and meet and greet the world has ever seen.There’s only room for 300 fans on this one-of-a-kind party, so don’t miss out."
"To reserve your spot on the Ronnie Mund Jamaican Getaway, you must place a deposit of $249 per person. There is also a $39 transaction fee. Since all rooms are double occupancy, the initial deposit for one room is $498 + $39."
