We are also considering a cruise on the Spirit in summer 2013. One thing that seemed problematic is that you can't seem to get a balcony cabin for 4 people - if you want to bring 4, and have a balcony, you need two cabins. Very odd. The ship also seems to have just one pool, and no adult only area. We are also considering a Carnival cruise with similar (but not as varied) ports - that ship seems much nicer, and they will let us cram 4 people into one balcony room!
