From reading all the posts about the vibrating cabins, we opted to play it safe and book cabin 645 on the Voyager, we were on a guarantee, but decited not to chance it. We were on the Voyager thru the Panama Canal last year on deck nine, (I don't remember the cabin number), but my husband noticed the vibration more than I did, I think the sleeping pills must help. We spent 27 days on the Navigator 2 years ago, and we were mid-ship , deck 8, our cabin was great...
Thanks for all the help.... ;)
