Hopefully me, but I asked that question, too (and I haven't heard back yet). I know that I could achieve Gold by having two "events" - can you do the same with one event and some number of nights (presumably less than 50)?

I wish you could get some credit for booking multiple rooms because I have a 5 room block scheduled in May (2 nights), this 10 room stay in June (1 night), and another 4 room block in August (3 nights). That's over 30 nights of stays that I'm responsible for, but I'm going going to get a total of 6 nights of credit for it. Those 32 nights plus my other personal stays would put me well over the Gold threshold.
