Practical tips

Use the result well

Use live refundable quotes with the same taxes, breakfast, and cancellation conditions.
Enter every guest and age; do not compare a correctly priced family room with a two-adult quote that omits children.
For two rooms, treat a connecting-room request as unconfirmed unless the property guarantees it.

Transparent math

How it works

One-room and two-room totals = nights × (room quote + breakfast per person).
Apartment total = nights × (nightly quote + breakfast + extra transit) + cleaning/service fees. Use equally flexible quotes.

FAQ

Questions this tool should answer

Is one family room always cheaper in Japan?

No. Scarce high-occupancy rooms can cost more than two standard rooms or an apartment-style stay.

Can children stay in a separate room?

Supervision and connecting-room needs are family- and property-specific. Do not assume adjoining or connecting rooms are guaranteed.
