Ok for the convention centre
To be honest, the only reason you will probably stay here is to attend an event at the convention centre or an event at the arena.
The hotel had very friendly staff who were always helpful. However, the hotel really needs an update, the decor is poor, furniture looks (and feels) dated and the general feel of the hotel is that a good lick of paint would be good. There is a coffee shop in the reception area and a reasonable restaurant. 
The wifi is quite poor, always dropping and they change the password every now and then without telling you! 
I would say there are better hotels to stay in around this area, most of which are either connected to the convention centre or about a 2 minute walk. The Drury's Inn and Red Roof are just two, I think the Hyatt is much more expensive. 
Overall, I think this is an expensive hotel for the quality. I have stayed in many Crowne Plaza hotels, and this is the worst one.
