So if I remember correctly there may have been hooks in-between the 5th sleeper and the bathroom on that wall but I may be confusing it with POR. Since the closet is the whole side wall in the bathroom, you can also get away with hanging towels on the hangers there too but for our family (4), I felt like between the drying line, hooks and hangers, we had no issues hanging all our towels. The dollar tree sells an extendable hanger with hooks attached, it's easier than sticking up command hooks. Might also find it at walmart. they're cheapy plastic but easy to use and store. There's a towel rack over the toilet, a towel bar next to the sink and I believe two hooks behind the bathroom door.
We had one luggage stand in the closet/bathroom area and if you could get one more you could put it near the door by bed. I'd ask if you really think you need it. That's where my kids put there cases since they also live out of their suitcases on trips too. Also, if you request a corner room, it's not vastly different in size but the extra window will help the room feel larger.
Touring plans has some decent room photos of you need to see areas/space. Also, if you google CBR room tour, you'll get some pretty thorough ones and even if they're from a few years ago, not much has changed in the rooms.
