We have this stateroom reserved in July. I've read a lot about this category 4e with extended balcony. I'm told it has a Murphy bed not the upper birth? Does this mean it's like a bunk bed? Or pulls down to floor? When I look at pictures I'm not sure where there is room to pull down a Murphy bed due to room space taken for extended balcony. I'm so confused. My kids do not like bunk beds but our travel agent says it Murphy.
