Depends on what you like to do instead. Plenty of phenomenal eats in St Helena and Yountville. Quick walk to downtown st helena which has some very good shops (IMHO an infinitely better place to hang out than yountville other than the restaurants...St Helena is much less, shall we say, extra). If you're a reader, the pool and your balcony will be awesome. I'm not as familiar with the hiiking scene on the napa side but i'm sure it's there and awesome. You could also explore the town of calistoga.

The alternative would be downtown napa, but that's completely different. Lots more going on in terms of shops and restaurants, but it's more of an actual town than "wine country." and the alila is just different league than the Andaz.
