sleeping at a baseball game???

Crae
Hi ladies! 
My husband and I are taking a vacation in August with our daughter. She will be 10 months by then. I didn't even thinking about bedtime when we were buying the tickets for the games. We are going to 5 ballparks And 4 of the games are at 7:10. 😱 my daughter is usually ready for bed by 730/8. Does anyone have any tips for getting her to sleep while there? Should we just adjust nap times to accommodate when we're at the games? 
#Mom fail for not thinking about her bedtime! 😣
