Do you have any tips for using milestones instead of XP for Tomb of Annihilation?

Do you have any tips for using milestones instead of XP for Tomb of Annihilation, given the sandbox nature?I’d suggest one level per location explored for reaching 2 and 3, then a level per two locations explored thereafter up to reaching ruins — Mike Mearls (@mikemearls) September 18, 2017
