event registration form

Who knows an event registration plug-in which can handle the following.

-group bookings, but the persons in one booking can select different type of pricing, like senior member or junior member
-add a sub event like “diner” or “excursion” to a chosen event and ad that price to the price of the main event, again each person in a group booking should be able to select a sub event.

We are working now with Event Espresso but we cant do what we like with that.

We are not looking for free plug-ins, buying a lug-in is no problem, even pay per registration plug-ins is an option.

Thx in advance
