Hi I am hoping to set off on my first cruise in March, but I am a little confused about how the beds are set up in the different interior cabins. I am using travelocity to set up the cruise and they are not clear about the bed layouts. When there is 2 dots on a rm it means that there are 2 sets of bunk beds? and 1 dot means 1 set of bunk beds? and I'm hoping that the rms that have no markings are just normal 2 twin beds that can be put together to make a queen? this is a dumb question but I really just need any help I can get. Thanks!!
