We recently upgraded to CS from Sky Suite on the Edge and loved it. With the changes to the butler service, we decided to upgrade and do not regret it. We paid $1k/pp for the upgrade and we loved the separate bedroom and our butler bringing our lattes every morning. Our butler and room steward decorated the room on my birthday and it was a lovely surprise. My husband is a night owl and I get up early, so having a separate bedroom with its own TV was great. Plus we loved the spacious accommodations. Like someone else mentioned, people would not bid if they didn't think it was worth it and we all have different levels of "worthiness" vs value. My daughter had a sky suite and enjoyed it (though she did miss having a butler - not that we ask them to do much more than morning coffee). So, in my long, rambling way, I'm trying to say that a sky suite will be just fine (and you'll have a great time), but if you can splurge for the extra space and butler service without seriously hurting your pocketbook, then go for it.
