Many wore shorts for dinner - it's quite acceptable on RiverBarge Excursion. I don't know if this is a hope or a myth. If you're in a storm, you will know it. No question about it - it doesn't matter which ship it is. Just as the shocks in your car, when you are on a rough road - you know.
Ships are like that too.
Ships are not like most cars. True, you won't find all the newest goodies on an older ship, but for most cruisers that is not really all that important. Everyone doesn't need an ice rink or a mini-golf course on a cruise.
