TOPIC: Is this possible?

I have a client that wants to set up an event as follows, and I want to know if anyone has any advice how to do it.

It is a three day event. Friday, Saturday, & Sunday. They want to manage capacity for each day. The kicker is that they have different "specials" that they would like to manage. They have a reduced rate if people sign up for all three days. A different reduced rate if people sign up for any 2 of the three days, and then a separate rate if they sign up for just one day.

Is this possible to setup with DT Register? How would some of you out there attempt to set it up?

To be honest, I haven't found a good way to do everything that they want. I can do all the price options they want, if I forget about managing capacity.

Any thoughts?
