Page Loads Slow With Multiple Maps

Page: https://utahcarczar.com/car-shows/upcoming-car-shows/

Background: Local car show listings page and I’ve re-designed the page to include a map of each car show location.

A handful of show listings already contain a map in the additional information (+ button) and that has caused the page to load very slowly. The more I add, the slower it gets.

I’m looking for a solution to this that allows me to keep maps on the page for each listing. Is there a plug-in or form of code I can add to speed up load time?

Worst case scenario, I will create some sort of image that will link to the Google map page displaying the location. But like I said, I’d rather look for a way to keep the maps on every listing. (fyi, could exceed 200 maps on the page)

Please let me know if I can provide any additional information.
