Thanks for the response. I had already called RCCL and they told me the doors DO have a removeable key locking system. Nice, huh?
My kids are 5 & 7 so they are too young to put in an inside cabin across the hall, but thanks for that suggestion.
Do you think there is anything I could bring that would be able to prevent the door from being opened?
How do the doors open? Is it one door that latches to the wall, two doors that latch to each other? Do the handles seem like they could be fastened together with a bike lock or a bungie cord or something?
This will be our first cruise on the Liberty and we were initially planning on getting connecting rooms on Deck 3 but we noticed they are on the same deck as some bars/clubs. I have posted a message asking if there is a noise issue on that deck.
