In my humble opinion your best fireworks ending spot is Poly - it has the most flexible options to adapt/adjust based on conditions. As mentioned above, some tables at Trader Sam’s Tiki Terrace have a view, but some don’t. But one can easily grab to go drinks at the walk up Tiki Terrace window, Tambu Lounge, or the Barefoot Pool bar and make their way to the beach for the best viewing. Between those three bar options for beverages and viewing space either on the Terrace, beach, boat dock, etc, it’s an easy setup to make on to fly decisions based on conditions you encounter. Have fun!
