One thing to consider about balconies that you may not have thought of: (although this may not be an issue for you, like it is for me.)
Every time we've had a balcony (at any hotel) I've been pretty much unable to enjoy it because of cigarette smoke from neighboring balconies. People tend to step outside to smoke, which is very considerate but with my severe asthma and allergies, it becomes a deal breaker for me when it wafts over to my balcony.
I know most people aren't bothered by smoke if it's not right in their faces, but just in case this was an issue for you, I wanted to mention it. For me, it would not be worth the hassle of switching my plans to get a balcony. It's not any fun for me.
