Everyone knows Traveling from kanto is 2 ways one is using ship 5k and other is via land water , and traveling to hoenn is 2 ways via johto, nap island and hoenn or ship but sinnoh is only 1 way only ship take 5k for one time for return 10k why dont u add some other island between hoenn and sinnoh or add a island between kanto and sinnoh and those island make a quest :) Its just my suggestion and try to decrease All traveling costs like from 2.5k to 1k to regional trasport and for other regions from 5k to 2.5k then every one use these ships and teleport items and try to decrease these Travel Pass price .TQs :)
