Do you plan on staying and cruising in Europe, China, The Med, or coming to the States and maybe Alaska or the Caribbean? Many of Royal Caribbean's cruises are 7 days, some shorter; it truely depends on where you wish to go, and from which port you want to sail from. I believe that, to get a cruise that would be more than 13 days would probably be a repositioning or a trans-atlantic, either from the US to Europe, or the other way. For a smaller ship, MY recommendation would be a Radiance class ship. Nice, and my wife and I described our first time on one as being slightly more "elegant" (classy or pretty). Our Favorite size are the Eagle, or Voyager class ships. Either way, and which ever ship and cruise you choose, I know you'll love it, and will be hooked!! And your English is just fine.
