When you are in town specifically for an event or events at the Smoothie King Center you would, in a perfect world want to stay as close as possible. Why waste time commuting to and from when you could be spending that time enjoying the action?
In the general proximity of the Smoothie King Center there are great hotels of all shapes and sizes, with different price levels, amenities and styles. Whether you want to treat yourself to a swank hotel with a full service concierge, or would rather save that money to spend on po-boys, you have options.
The closest hotels to the Smoothie King Center are the nicest ones. The Hyatt Regency and Le Pavillon are quick walks away, yet very different sleeps. The Hyatt Regency is super modern with tons of space and great views. Le Pavillon is all opulent formality in a fabulous building dating back to 1907.
There are more "budget" types of hotels close by too, offering the handy option of being closer to attractions by the river and the French Quarter. If you want to save some loot, and imagine yourself splitting time between the Arena and the Quarter, checking out these types of hotels would be ideal.
