The Hyatt is a lot like most other. It is a huge building that is very extravagant and beautiful. Our stay there was very pleasant. The rooms were sizable and very clean.
The Superdome is very close and there are two restaurants inside. The location puts you within walking distance of the French Quarter. We took a cab out, but ended up walking back to the hotel at night. The route back is sort of deserted, because you're close to the business section, but seemed relatively safe.
The night's stay was excellent and the hotel would be great for a business traveller, but I wouldn't recommend it if you really want to experience New Orleans. There are too many interesting small hotels in the Quarter that are less expensive.
