The Grand Hi Lai Hotel in Taipei has a Hello Kitty Suite, Hello Kitty Rooms and also a Hello Kitty House in its lobby.
The Hello Kitty Suite: Featuring a living room, dining room and a master bedroom, this 50 square metre Hello Kitty themed suite is very pink! It is decorated - as you would expect, with many Hello Kitty objects from vases to paintings including a complete Hello Kitty tea set.
The Hello Kitty Hotel Room : The hotel room is slightly smaller, as you would expect - it is fully furnished with pinky Hello Kitties everywhere including curtains, tables, chairs, and bed. The desk comes with a Kitty lamp, Kitty postcards, notepads, Hello Kitty letter paper and Hello Kitty envelopes. Hopefully they also have Hello Kitty Coloring pages! There is also a complete set of Hello Kitty personal amenities including slippers, towels, bathrobe and bathroom accessories. Cute!
The Hello Kitty House: The Grand Hi-Lai Hotel has partnered with the Sanrio Corporation of Japan to present the 'Hi-Lai Kitty House' which you will find in the hotel's lobby. Nearby is a gift shop where Hello Kitty limited editions and gifts are sold. All the Hello Kitty amenities provided in the rooms are available in store.
