We were there in June of 2021 when the country was just opening back up after Covid. It was crowded.
You might try to get there early in the morning. It gets more crowded as the day goes on. If you have not been before, see Old Faithful and Mammoth. When you have seen one geyser, fumerole, mud pot, and hot spring you have seen them all. Unless you’re hiking, fishing, or doing something else, a week will be overkill.
A couple of days should be enough for sitting in traffic and seeing thermal features.
Pack a lunch and have a picnic each day. This lets you avoid crowded eating places. You’re not there for the food.
I’m not sure what the road situation is after last year’s flooding. You might want to Google the current conditions and adjust your route accordingly.
While you are on the website you can check information about pets.
Enjoy your visit and the time with your family.
