Magical Vacation is an adventure RPG for the Game Boy Advance. In the magical kingdom of Kovomaka, war erupted for three days, but it was kept a secret from ordinary citizens. A man traveled all over the country in preparation of the next battle. Several years later, the player starts attending Will-O-Wisp, a magic school, at the principal's invitation. The player has the ability to interact with spirits. The class is sent away to summer school by the Valencia seaside, where schools are said to have gone missing. A monster called an Enigma shows up on the beach and abducts several students, whom the player must find and rescue.
The gameplay involves exploring a map divided into four plains, each with its own terrains and inhabitants. The player battles enemies in turn-based battles, where strengths and weaknesses depend on element. In addition to solo play, there are three multiplayer options: Let's Amigo, Let's Onsen, and Let's Taisen. Amigo allows players to exchange spells, while Onsen lets players access each others' hot springs to power up. Taisen is a multiplayer battle mode.
