Hi! I'm getting ready to sail on my first cruise ever. I am definitely "pooh" size, carry a lot of weight in butt /hips/thighs. I was looking at pics of the Walt Disney Theatre on the website and it looks like there's no way my butt is fitting in them. Do the armrests go up? I'm so stressed now I want to cry. Anyone have experience with those seats or any of the seating on the Magic for that matter?
