The basic cabins on Ruby Princess are comfortable but not overly spacious. One of the standout highlights are the beds, which Princess is known for. These "Luxury Beds," as they are called, really are comfortable, whether it's a twin (which is a bit on the small side) or queen. My kids are not great sleepers and yet they slept beautifully each night (and it was hard to wake them up).
Basic cabins have two twin beds that can be pushed together to form a larger bed, a desk, two closets, flat-screen TV, mini-fridge and hair dryer. There's plenty of drawers and closet space for two to three people.
Rooms have just one or two electric outlets, which is tough for anyone traveling with a slew of electronics. If that's you, bring a plug with multiple USB outlets (just make sure it's not a surge protector because those are not permitted on cruise ships).
