Here is how where you can farm more festival points, Festival Coins and bottle caps in the Festival Plaza in the "Pokemon Sun and Moon" according to iDigital Times. The Rare Kitchen might be useless to be obtained by the players for their Festival Plaza where they can only farm bottle caps one at a time and will waste so much time but will be a major source if players want to increase their Pokemon's stats.
The "Pokemon Sun and Moon" players have to obtain the Rare Dinner, which can give them up to seven level-ups for 100 Festival Coins. If players can reach their Pokemon to level 100, they can get the Hyper Training where they can trade bottle caps for IVs to Mr. Hyper in Hau'oli City. However, it only works when your Pokemon reaches the maximum level.
