Yes you're spot on.

That was the especially disappointing part as people from smaller places without established dommes look forward and make plans well in advance to see famous/world famous dommes.

And that means an opportunity cost to not see another equally well known or established domme.

When the plan is cancelled at the last minute, one loses not only the $50/100 deposit, but also end up sitting in the hotel room wasting the time, especially since another well establisehd domme would not accept a last minute booking on short notice.
