Like the others said I would ride Remy first then if the wait isn't that long you can do frozen without much of a wait... if Remy's wait is pretty long when you get there (i.e. you arrive for early entry but you're pretty far back in the crowd) then you may want to go to frozen but you'll be behind those that were closer coming in through the main gate. Let us know what you end up doing and how it goes!
