Since I don't have kids and cruise out of California. My old butt couldn't get quarter of the way up the rock climbing wall.
I'm way to cheap to pay extra for a steak or a hamburger and I like new ship Carnival is my cruiseline. I think our biggest differences have to do with point of view.
With kids and crusing from Florida RCI is a better fit for you. This is truly what I love about cruising, there is a cruise line to suit eveyone. I still wish RCI would send the Freedom of the Seas out here to cruise LA to Hawaii 14 days I could test it out. Maybe after 14 days I could make it halfway out the wall climbing wall.
Part of the reason the big ships don't come out here is because they don't fit in the Panama Canal, they have to come the long way around.
