Is there any major difference between the Overwater Horizon bungalow and the end of the pontoon bungalow? I know the end of the pontoon ones are at the end of the row - but the physical rooms, any bigger or nicer? I have some reward nights booked for the beach bungalow and will be paying to upgrade to OWB. I do not plan to be going to Bora Bora often given its location and cost, so as a 1 time splurge I am fine paying the upgrade fees, the question is it worth ~$150USD a night more for the end of the pontoon vs the horizon OWB?
