I went on Saturday, and it was quite crowded. Once inside, you had to scan a QR code to get a photo opportunity with the characters, and that was only available for the afternoon. The boat parade pass was also only available for single people. It's an indoor amusement park, so there aren't many attractions. There are shows to watch, and you can eat various character-themed foods, which are very cute. There are also shops, Ichiban Kuji (a type of prize), claw machines, gashapon (capsule toys), etc.
