If you're a fan of 'Ohana, order the Twilight Feast from the room service menu and eat it on your balcony. Portions are very large. You can get just one meal and share. The adult portion ($40) will definitely feed you both, and the child portion ($20) might also if you're not big eaters. It comes with everything you get at the restaurant except the ice cream for the bread pudding. Room service will have added the gratuity (18%) to the bill already when they give it to you to sign. But there's also a line on the bill for a tip. Be careful not to tip a second time!
