Wait what does it mean to do all 4 parks “commando”?!? I can only think of the definition from Friends
I think there’s a ton of personal factors that would influence your decision. How much time will you send in the room/on the balcony? What would you do with the $75/day instead- maybe spend it on a special Disney add-on experience instead?
For me personally, we are rope-droppers and any time that we spend at the hotel is at the pool. I would stay at BC, take the money and put it towards making lightsabers or the caring for giants tour.
