### 1/5 — キャンペーン参加

*2026-04-24*

全てにおいてわかりづらい
キャンペーン参加方法もマイページにたどり着くのも一苦労。参加してあるかもわからない、マイページのタブを下のところとかに作ってほしい

### 3/5 — 読み込み長すぎ

*2026-04-11*

ホテルを予約する時の検索待ちが長すぎます
長すぎて、他のところでもいいか…となるレベルで長いです
候補のホテルの数が多くても少なくても読み込みはとても長いです
しかも読み込み失敗になる時もあるので、フラストレーションが溜まります

そのほかはデザイン等使い勝手いいのでマイナスポイントすぎます…

### 1/5 — あまりにも遅い

*2026-03-31*

過去、三井ガーデンホテルを利用していましたが、予約アプリが遅すぎて、使いものにならなくなりました。仕方なく、他のホテルに宿泊せざるを得なくなっています。早期改善希望します。ホテルは良いので宿泊できないのは残念です。

### 1/5 — 一向に改善されない検索速度

*2025-12-22*

以前はそこまで不便でなかったのですが、今は非常に使いにくいアプリになってしまいました。
とにかくホテル検索の時間がかかりすぎる。
長い時間待たされてエラーや少しでもアプリを離れて別のアプリを使用するとエラーとなる。
時間がかかり使いにくいくせに、アプリに張り付くことを要求してくる。
割引クーポンを出すより先にアプリを改善してもらいたい。

### 2/5 — ロードが長すぎる

*2025-12-15*

アプリができた頃はまだ拙いながらも使えてましたが、とくに見やすくなる訳でもなく、ロードだけが長くなり、ついに今日は長いロードに待たされた挙句のエラー
公式サイトには空室ありました。他社の予約サイトにも出てました。
そろそろ抜本的に直していかないと、使えなくなってくると思います

### 1/5 — Registration is Flawed

*2025-11-20*

Will not accept phone number in any format.

### 1/5 — 予約検索画面で固まる

*2025-10-06, version 6.12*

価格を調べようと予約すると画面がローディングのまま固まります。改善してほしい。。。

### 1/5 — Can’t register email

*2025-10-03*

Doesn’t send registration email

### 1/5 — 検索できない

*2025-09-09, version 6.12*

ホテル予約しようとしてもエラーがでて全く検索できない。管理されていないのかな。せっかくの公式アプリなのに残念です。

### 2/5 — 使いにくい

*2025-08-22*

予約画面の開示が遅い。しばらく待っても表示されない。

最低限の予約機能は動作の検証をして欲しい。
また、外資系ホテルのようにApple Walletへの会員証追加機能の対応をして欲しい。
