We are planning to book the All Star Scuba Scene for our next liveaboard. They have cabins on the main deck and upper deck which appear very similar to. The entry for the main deck is through a central hallway while the upper deck rooms have an exterior entrance. I like the idea of an exterior entrance but am curious if anyone has experience on the Scuba Scene and can provide some insight. My concern with the upper deck cabins is whether they will experience more motion than the main deck. Any feedback on the cabins on either deck is welcome.
