For convention centre try Atlet Century Park
1Ball,
The Mecure is a long way from the convention centre. The Atlet on the other hand, is a fairly casual ten minute walk through the park from there. Added benefits of nearby shopping malls and the Busway close by to get elsewhere. Rooms from $50 USD all inclusive on [url]www.wotif.com[/url]
The trip back and forth from Kota gets a bit wearing from there, but seeing there won't be much up that way for the next month, there probably isn't much reason to stay in that area when you need to be elsewhere each day.
