First, let's get this all out of the way. We're from Iowa, and winter in Iowa (especially this winter) has been very cold! Needed a getaway to somewhere warm, and a caribbean cruise fit the bill just fine.
We've now cruised a total of 3 times, twice on Carnival, once on Norwegian, so we're not experts, but we aren't complete neophytes either.
Why have we cruised twice on Carnival? They go where we want to go, and their prices are almost always less than everyone else. So, yes, we are what you might term "value cruisers". We still appreciate nice stuff, but, at then end of the day, we don't need the very best of everything, as long as its pretty darn good. And, the Glory is definitely "pretty darn good".
Room is nice. Typical Carnival, with very adequate space, good storage, small but ergonomic bathroom. Close to elevators, nice view out window. Quiet, never heard noise from anywhere outside the cabin.
