My favorite is definitely the FREE room service on Carnival. The food is sooo good and it's not offered anywhere else on the ship but through room service. The second would be the balcony. The last time my husband & I and his brothers got three rooms in a row so we opened up the partitions between us so that we had one HUGE balcony. It was awesome!

Breakfast on the balcony every morning was my favorite!

I'm in desperate need of a cruise!
