If you're using the dining plan and want to free up a TS credit, you can also get Tonga Toast at Captin Cook's and use a QS credit.In my opinion, I would do Prime Time as its a blast and if you play with the servers it's a blast. Liberty Tree is one of my daughter's favorite and chose that for her 10th birthday dinner. Crystal Oalace to me is a rite of passage as its right at then end of Main St USA and seems like a must do at least once. As far as Ohana and 1900.... We like both and hard to compare. 1900 Buffett at either breakfast and dinner is American fare with characters, where Ohana is character in morning but at night a fun night of constant food coming to your table....noodles are awesome. I would also suggest Kona at the Poly for breakfast. Never make a trip without going there. Tonga toast. Yum. Take a look at Boma for a great Buffett also. With this all being said, you will enjoy no matter what. Food isn't always 5 star, but always fun. Enjoy!
