Manza Prince Hotel
forumWhat families say
Rakuten Travel rating 3.77 out of 5 (2,085 reviews). Several guests report a comfortable stay in the cool climate, around 20 degrees C even at the height of summer, and praise the buffet as delicious. Some also report that families with a child who has allergies were able to stay comfortably in a clean room. On the other hand, the open-air bath includes mixed bathing with a towel-wearing rule, so guests who would find that uncomfortable should keep it in mind.

Manza Prince Hotel is a large resort hotel with 227 rooms in total. For families, the Main Building Family Room (38.0 sq m, for 1 to 4 guests) has 2 main beds and 2 sofa beds, giving everyone room for a lively stay together.

The 10-tatami Japanese-style tatami room (for 1 to 5 guests) comes with 5 sets of futon bedding and has no bathroom. The Main Building Family Room, Main Building Twin Room A and the Japanese-style tatami room each come in both non-smoking and smoking versions, so if you want to avoid tobacco, specify a non-smoking room when booking.

Dining
The restaurants offer menus for children. With some accommodation plans, dinner is a children's dinner, either Western or Japanese. At the buffet restaurant, a child rate applies from age 4. Food allergy accommodation covers only 8 ingredients - shrimp, crab, walnut, wheat, buckwheat, egg, milk and peanut - and must be requested in advance.
Baths and Onsen
At 1,800 m above sea level, the open-air bath Komakusa no Yu is a communal bath where you can take in the seasons - fresh greenery, autumn leaves and snow views - and a sky full of stars at night. It includes a mixed-bathing tub, where towels are worn, so couples and families can bathe together. There is also the women-only covered open-air bath Shakunage no Yu. If you would rather soak as a family in private, the private-hire onsen baths on the 1st floor of the South Wing, Suisho no Yu and Shirataki no Yu, cost 3,000 yen for 45 minutes and can be reserved at the front desk or by phone. Guests can also use the onsen at the sister property, Manza Kogen Hotel, free of charge.
