Kids get a Kids Passport with coloring and puzzles when they arrive, and the 20-meter heated indoor pool is up on the 39th floor.
Artificial mist rolls through the Meiji-era garden like a sea of clouds, with a three-story pagoda rising above it and a thousand lights after dark.
The big Roppongi Hills hotel, with an indoor pool, and the Mori Tower, the cinema and a dozen places to eat right outside the door.
Renovated rooms and lobby, a 7-Eleven under the hotel, and a giant playground a few minutes' walk away.
Apartment-style rooms with a kitchen and a fridge, which with small kids in Tokyo is the whole point, a quiet walk from Shibuya station.
On the 38th to 43rd floors, with living walls of plants and a family package with an in-room kids' tent and wooden toys.
