Twilight receives a very unusual and special letter from the Princess, requesting that she and her friends take a vacation. The contents? Nine tickets to a pre-paid week trip to the vacation island of Monta-Kai.

What makes Monta-Kai so special? The magical island is split into two sections: First is a tropics section, with a beach, clubhouses, cottages, campfires, and outdoor sports. On the other side is a snow-covered mountain, complete with skis, snowboards, and local and private cabins.

Twilight, Applejack, Rarity, Rainbow Dash, Fluttershy, Pinkie Pie, and the Cutie Mark Crusaders come to the island, expecting a week of fun and relaxation. But not without a few surprises, of course.

What type of surprises? Well, we'll just have to wait and find out.
