Serene, I booked 6232 on the Pride; I really wanted that one. I felt the HP cabin was more apt to be "taken" away than a Quad as there are many quads available but HP's are rare although 6234 opened up, too.
Because I like to know exactly where my cabin is and not to have to fret over it for any length of time, I pick a cabin that we can live with and enjoy. Only once did we do a Category guarantee on a Princess ship and all the cabins accept one were sold out. We got a 3 category upgrade and it was a good location. I stressed over it so much, it wasn't worth the worrying. Always check out the diffence in cost from the lowest acceptable cabin category (guarantee) and an assigned cabin in the same category or higher. Sometime the difference isn't that large.
