My only hesitation about doing Carthay package is that it does take 2 hours to eat. If you're only in the park a limited time, do you really want to spend 2 hours of it eating? If you're ok with that, then the food at Carthay is great. The ambiance is also really nice, but keep in mind that it's still a Disney restaurant and there will be the usual tired, not so well behaved kids there even if your own 2 year old is home asleep. When DH and I went alone, we had a drink in the bar first and I recommend that as well. It's been a couple of years since we did the dining package, so I can't answer the view question -- don't really remember and it may have changed since then.
We like doing WOC Dessert Party instead now because I don't like to spend the park time at a restaurant and I like sitting for WOC.
