This is going to sound soooo unromantic but...
We honeymooned in WDW back in 2003 and could not get a king bed. Instead of making this a negative, we decided to take advantage of this fact and we each took a bed to ourselves...not every night...
...if there are only two of you in the room - just saying - while not romantic - it does make for a really really good night's sleep.
My hubby is a bed hog. I'm 5'1" and he somehow makes it so I have no room in our king bed at home. I fear I'm gonna fall out of bed one night...! It was a wonderful break to be able to stretch out after walking all day!
