Which Non-Haven cabin category is best for 4 adults?

Took my first ever cruise on the Getaway June 6-13 and had absolutely the BEST time and can't wait to cruise again. I took my Mom (her birthday present) and my 18 yr old son (his graduation present). We had a spa balcony cabin (B9) and had plenty of room for the 3 of us, even surprised at how much storage space we had left over after unpacking.

Now we are thinking of taking a cruise in November 2016 for my 50th b-day celebration, but will most likely be a party of 4. I know some of the standard balcony cabins sleep 4 with the pull down bed, but thinking we might need just a bit more room with 4 of us. Which cabin class should I be looking at for Getaway or Escape?

Family ocean views with large window sleep 5 and are pretty spacious
