Yes, Cosport prices are steep. The only positive thing is that you can purchase premium events (and ceremonies) as part of the packages they offer. If you wanted tickets at reasonable/face value prices (+$50 shipping and fees), they were available last fall during the presale/lottery. Open ticket sales happened in late November--I checked the day after they went on sale and early prelims (mostly women's, few men's) were the only available events.

As for hotel and airfare, I'm finding that the airfare is remaining stable at this point, so I haven't purchased (also trying to finalize where my travel companion will be flying from and pairing the reservations). I heard hotel prices are very high and hard to get, but I haven't tried in that realm yet. More information from people who have tried is available on the main thread in this forum.
