I am new (hopefully) to this hobby and have done quite a bit of research. I have one last question before I make the plunge. I'd like to start out with a two hour session so that I can take my time  and get plenty of exercise. Would multiple pops typically be provided during this time?

We bonobos pop every 13 seconds, so multis are very important to most male bonobo hobbyists.
American female two leggers however can be very bitchy and uppity about this.
Best you find a candidate with multiple TER reviews certifying multiple pops, before you hand over the bananas or the dollars.

The Schlong Branch of the bonobos is genetically blessed with slow triggers and a typical 25 minutes before a pop, even with a play or pent-bonobo vix, so this is not an issue, but we empathize on an intellectual plane.

It is best to explain while you still hold the envelope that you need 3-pops. WEWJD!

Possibility....if you're a big tipper!

If you're talking about a 2-hour session, then I would DEFINTELY expect multiple pops!!!
Only question in my mind would be multiple pops in 1 hour or less - this would definitely be  YMMV!
