If you book a stan, stan poolview, or sav, the bunkbeds are a request only. We have stayed there 2 times and we have had bunkbeds. It's our only request besides non-smoking for medical reasons so really it's one request. That's the most important thing for us so it's the only request we've made. We had the bunks and great views too.
I should add a funny conversation with a CM at CRO when I double checked the bunk request. She said it was only a request and we could end up with 2 queens or a king. I said "no" to the king and she told me we could get a king...I said with 4 in a room? She said, "hmm, 2 queens or bunk beds it is then."
