We've been in mid-November twice and while it was manageable, we were still glad we had EP. I would probably stay where you want to stay at Cabana Bay and just purchase EP. Not sure of your exact dates but a lot of the dates in mid-November show the unlimited EP for $85-$89pp per day. It shouldn't be too much more expensive than if you were to stay at RPR. Another option is to go in without them and just purchase them there in the park if you feel as though you need them.
