I usually want a good view. I pay for it and don't request anything.
The time it was most important was when I specifically booked a water view for mom, who was making her last trip to WDW. She couldn't spend much time in the parks and said she'd be happy to just do a little and spend a lot of time sitting on the balcony - reading, reflecting and looking at the view.
So, OF COURSE, that is the one time Disney screwed up and didn't give me the view I paid for. They promised we could switch the next day, but then that got screwed up, too.
It finally became more trouble than it was worth...and upset my mother...so we gave up.
I attempted many times to get that money refunded...but then they offered something for the next trip...after I'd already told them that the previous one was her last. I had to hang up, I was so angry and upset.
I've received several room upgrades over the years that I didn't pay for, so financially, it's a wash.
But I still get ticked with them when I think about it.
If the view is seriously important to you...now or never kind of thing, stay on top of them. Don't check in until you're getting it.
