Norwegian vs. RCCL or Celebrity?

[CactusGirly]

We are looking at a late fall cruise on the Getaway, but have never sailed on Norwegian before. We have cruised with Royal Caribbean and Celebrity in the past. Wondering if anyone has experience on these could compare and contrast for us?

 

This will be an adults only trip and what is important to us is great food, nice cabin, places to relax, and plenty of smoke-free areas.

 

Thanks in advance!!
