Traveling with toddlers, how many days?

I’m planning a trip for summer of 2026, we’ll have a 2 & 4.5 year old with us. I found a beautiful Airbnb right outside the West entrance for ease.

Now how many days should we spend in the park? My husband and I prefer slow travel over packing it all in. We’d like to do a day or two, then take a break for a day, and potentially do another 1-2 days.

Thoughts on how many days we should reserve for the park?

On the day off, we’ll probably explore Whitefish, then we’re heading north to Banff/Jasper area for approx 2 weeks. We have between 3-4 weeks available for the whole trip.
