Hi Judith,
Q: Is it possible to bundle a certain number of Events and sell them as one?
A: By default, Pass to Event is N:1 relationship, which means each pass could be only binded to one event.
But a pass could be applied for sessions from different events.
Q: Is it possible to offer a pakcage taht includes a table for 8 members for each event?
A: As per my standing, does your requirement means that a type of pass which could include 8 people inside one registration?
If so, each event registration record could be only binded to a specific contact too;
But event website visitor could add multiple people in one time registration process.(It will obviously create multiple registration records for each person)

As screenshot above, a visitor could see all registrations before Checkout,
so you could add customized validation with javascript on Event registration page, for example, you create 2 types of pass:

A visitor could be allowed to checkout only when he has added 10 people with same specific pass(Team Bundle 10 people).
