Madison or Bridge Bay w/2720sl

Hello All! It's been a while since Gary and I have been on here, however, we hope everyone are doing well.

We always turn to the board for insightful information that can be trusted and need your advise again.
Traveling to Yellowstone at end of May beginning of June and wanted to know which facility is more desirable ~ Madison Campground or Bridge Bay Campground? Hope to hear from you soon. Thanks a bunch and happy camping!
