Not sure if pricing changed but i was there on 11/11/2017, and it was ~$20 for a single race and 3 races for ~$50. I don't know about the trampoline prices.
It would be easier to call them to see how much it costs to do what you want to do
It varies from first time $28.00 to returning is $20.00 per race.
Trampoline Park is $8 for 30min, $14 for and hour and half priced on mondays
There are different psckages
