My family unanimously agreed they want to start our trip in
Disneyland as it's the most iconic of the two parks. Then we are just going to alternate parks each day. We have park hopper tix so we can basically just go with the flow. I'm hoping to get OBB tix on a Tuesday night which falls on a DL day. But I'm thinking we would do DL in the morning, take a break while the mix in is going on - probably eat, change into costumes, etc. Then go into DCA just before OBB starts.
Of course this plan could all go to hell once actual OBB dates come out. lol
