I did an search and can not figure out the ans to these ques. TIA for the answers. 1. Do some of the cat 5 have a pull down bed and others do not? Which rooms have a pull down? We are 2 adults, 2 kids and want a cat 5. 2. Can they put bed rails on the lower convertible sofa bed? 3. Are the verandahs clear plexi or solid? 4. Has anyone ever sailed a cat 4 and THEn a 5? We did the 4 and loved it but it is quite a price difference so....we are thinking about the 5 this time. 5.
