Daughter’s party will be held during her normal nap time

Tomorrow my daughter is having her first birthday party. When we originally scheduled the time, we purposely picked the times in order to avoid her (then) nap time schedule. Now, her nap schedule has changed, and lately she is napping at the time the party is set to begin. I’m not sure how I should navigate this. I really want my daughter to have a good time, and I don’t want to have a grumpy baby to take care of on top of hosting a party! Normally if she skips naps she is very very fussy and irritable. Anyone have any tips or pieces of advice on how to proceed???
