Haldyn Hotel

The "Haldyn Hotel", also referred to in the song's lyrics as "the Jardín of Trujillo", is inspired by the Los Jardines Bungalow Hotel, located on the city of Trujillo, northwestern Peru. The location came to Hirasawa's attention through a book on "holistic health" he read on a holistic ramen restaurant in Kameari, that contained interviews of doctors who researched magical practices in folk medicine and visited descendants of the Inca who preserved their traditions; during this trip, the doctors were headquartered in Los Jardines. At some point, Los Jardines stop operating, and its address is currently occupied by an Open Plaza shopping mall, run by retail giant Falabella group. One of the verses invokes Odic force and Dowsing.

Versions
An Andean-influenced march with an intro consisting of train sounds (similar to David Bowie's "Station to Station" and Kraftwerk's "Trans-Europe Express") The bridge heavily features two Crumhorn lines, one performed by a professional wind instrument player, similar to Hirasawa's guitar solos, and the other by Hirasawa—who had little experience with woodwind instruments—that consists of a single repeating note. On most live performances Hirasawa would improvise a guitar solo instead of using a crumhorn. A brief snippet of the song's intro melody was posted as a "Standerd [sic] MIDI file" (uploaded on hqx, lha/lzh and au file formats) on Hirasawa's "Ghost Web" site in 1995.

The second half of "FGG", the track that precedes this song, is an extended intro for "Haldyn Hotel" as debayashi for the core live band. Features, besides the band, live orchestral backing and a Wind Synth solo for the bridge in place of the crumhorm.

Follows a story segment from the Interactive Live Show, and stars with the opening "HA!" projected on screen right before it falls down to reveal the band. The guitar, bass and drums are heavily prominent in the mix. The overall band arrangement is different from the error version, particularly on drums and bass, due to member changes.
 * Making of Tokyo Paranesian, 1994
 * TAKA - keyboards, backing vocals
 * Toshihiko "BOB" Takahashi - fretless bass, backing vocals
 * Wataru Kamiryo - drums

Hirasawa sings different lyrics for the last repeat of the chorus. For the bridge, a soprano sax solo is played.

 * TAKA - keyboards, backing vocals
 * Toshihiko "BOB" Takahashi - fretless bass, backing vocals
 * Kazutoki Umezu - soprano saxophone
 * Tadahiko Yokogawa, Youko Honji - violins
 * Wataru Kamiryo - drums

Rearranged closer to the style of the Sim City album. Thai vocal parts are inserted before the chorus, and on the first time it comes up Hirasawa makes a "shushing" gesture to prepare the audience for the change and to not sing over the Thai parts. The guitar is high on the mix and train samples are played in place of the crumhorn solo.
 * Sim City Tour, 1995
 * Susumu Hirasawa - vocals, electric guitar, Tubular Hertz
 * Miss N - Thai vocals

Arrangement close to that of the Sim City Tour.
 * Unreal Soprano, 1996
 * Miss N, Miss Aeh - Thai vocals

Also following the Thai style. The Thai vocal comes in between the train noises and the intro, after the bridge and throughout the coda. The core of the instrumental arrangement is the Water in Time and Space one, with added percussion flourishes and a new synth bassline that pops up on the second set of verses. A horn solo is played on the bridge, which is finished with Hirasawa flatly uttering "pai duai" (ไปด้วย). This version was released as a free MP3 to promote the album.
 * Switched-On Lotus, 2004
 * Susumu Hirasawa - lead and backing vocals, all instruments
 * Miss N - Thai vocals (sampled)

The first arrangement without Thai touches since that lineage's creation. This version has a piano-based intro, with hi-fi synth strings and a percussion loop. The guitar solo, performed on Ice-9, has a unique sound. As the song ends, Hirasawa plays train whistle sounds on the Graviton.
 * Phonon 2550 Live/Phonon 2550 Vision, 2007

This has a symphonic intro with timpani and Misa Kitara-controlled Zeusaphone backing by the live band. Hirasawa sings his parts of the chorus while covering his mouth and headset microphone with his mouth, and the solo is performed on Zeusaphone.
 * Phonon 2555 Vision, 2012
 * Susumu Hirasawa - lead and backing vocals, keyboard, laser harp
 * Pevo 1go - Misa Kitara, Zeusaphone
 * Yasuhiro Araki - timpani

Connections

 * A bit of the song's intro was used as the coda of "Quit". Hirasawa would later do a similar technique with the also march-like "Parade" from Byakkoya - White Tiger Field & Paprika.

Trivia

 * A subway advertisement for a "Haldyn Hotel" appears in a scene of the film Perfect Blue.
