I also use events for 24 hour leveling. We're always worrying about token overlap, so as we approach the Welcoming of a new character we stop leveling up anyone else AND once you get to about the 3rd character, you know it's going to take at least 24 hours to collect their tokens. So that leaves a window to level up 1 or 2 24 hour characters. So for TLM event once we were approaching the Welcome Triton point, I started leveling others to 10, until I had the tokens to actually welcome Triton, again for the run up to Welcome Ursula and again for Ariel, and again for her costume.
