My family of 5 is going to the Southern Caribbean in August with the Serenade of the Seas - Royal Caribbean International. We'll be going to St Thomas, St Kitts, Aruba, and Curacao. Any suggestions on excursions? My mother is 76, husband and I are late 40's, daughter 15, and son 12. Also, does anyone know if the Serenade has a good teenage program. My daughter hasn't been able to find any info on this and she's freaking out.
