Christmas eve = no nap

Its been a busy day which means my 3 year didn't nap. She is a toddler that needs one or it's one tantrum after another. Bedtime is normally 8-9 ever night. I noticed she had been quiet about and ho check on her and she is out like a light. Its 6:30 so I'm torn do I let her just sleep or wake her up...

We have another long day tomorrow also so I'm torn
