I stayed at one in Montana and it was nice. The place was newer or upgraded and very clean, which I appreciated. The hot breakfast in the morning was nice and it had a nice pool and hot tub. Next time I travel I'm likely to revisit.
United is alright I guess. Not the worst. My flight didn't feel like anything special or anything. There was trash left in the back of the seat in front of me when I got in last time. Pretty typical flight though.
Southwest is like a discount or clearance airline. Every time I fly with them I feel like everyone on my flight got their ticket from craigslist or groupon or ebay or something. I can't put my finger on it.
