This is great news, it is a massive property down by the river in Jacksonville.

Competition is virtually non existent there, there is a Hilton on the other side of the river and a Radisson and the Plantation Manor Inn, which is the only property in town with a AAA 4 Diamond rating,however it is a B&B.
Beside that the competition on the beach in Amelia Island and the Marriott Ponte Vedra Beach is certainly strong, Sawgrass Marriott PVB is hosting quite a number of conferences...

The Hyatt will be by far the biggest hotel in the region, a great addition, also because rates are really cheap on the weekend, stayed at the Hilton for $ 69 a few years ago and I can imagine that the Hyatt will also be well below $ 100 on weekends...

JAX is indeed growing like crazy and is sometimes mentioned as an outsider candidate for transatlantic expansion from Europe...
