Family-friendly accommodations in Nikko for autumn stay with young kids?

Hey fellow travelers! I'm a parent planning a family trip to Nikko this November to catch the stunning autumn foliage. I'm looking for budget-friendly accommodation options that are safe and convenient for my little ones. Any recommendations for cozy hotels or traditional ryokans that offer family rooms or special amenities for kids? I'm trying to keep our accommodation costs around $150-200 per night to fit our family budget. Any tips on booking in advance to secure the best deals during this peak season? Thanks in advance for your advice!
