If you upgrade to FAS Plus, you get Starbucks, top-shelf liquor, unlimited wifi, excursion credits, and additional specialty dining meals. At $49pp/pd ($42pp/pd if solo), I consider it worth it even though I don't necessarily care about the premium liquor. I just can't survive without wifi, appreciate having specialty dining, and would otherwise spend $100 on coffee over seven days, so YMMV.
