We finally did this in December and it was so much fun!! I love being up high and it was a great vantage point for the Disney Springs construction! It does shut down a lot because of wind, so beware. Our anecdotal experience is that it is more likely to be shut down later in the evening than in the morning or afternoon, so go kid of early for the best chance at riding. We went around 2pm and the wait was very short.
There was a Groupon for $11pp or $20 per couple. Not sure if you can still buy it or not. It's good through April 23, but if you miss that deadline, you are supposed to be able to apply what you paid toward a regular priced fare anytime. I bought one because if we can't go during our April trip because of weather, we'll use it in September and it won't cost us any more money than it would have otherwise.
