The conference space at the Mason Inn was too small (or at least the largest ballroom was), some events that Mason academic departments wanted to host ended up being over-crowded and had to move off campus. And the rooms were too expensive for visiting families (not worth the large extra cost for a small increase in convenience) but yet they didn't get enough business / academic guests to cover costs. I don't know if any hotel is viable, but they certainly built the wrong size/scale/class of hotel last time around.
