I do feel for you, if you do worry about these things...
But please, don't worry about any of the opinions given by us dorks (self included!) here on these threads! WE'RE the ones with the problem!
Remember, only a very minute fragment of cruise passengers troll these threads. Who cares about what we have to say? All the 'normal' people don't bother. They just go, & have a good time & enjoy themselves. As my dear, departed mother-in-law used to say ..."ta HELL with it!"
You be one of THOSE people ...please!! :)
