Hoping it's Alola since I am doing a wonderlocke...

This is what you get if you just count the numbers in the numbered routes. Hoenn: 34 Sinnoh: 30 Kanto: 28 Unova: 23 Kalos: 22 Johto: 20 Alola: 17 There goes your hopes. source If you have a slightly different definition of a route, then just tell me and I'll hide this answer.
