By being thrifty, we can cruise twice a year (maybe three times this year, fingers crossed) instead of only once. I at least want an ocean view for the natural light, but we don't have to have a balcony or a suite. We don't spend much on the ship or in port, but we enjoy ourselves. I wouldn't cut back so far that we felt deprived of a great experience, but we don't mind doing without the extras (except my specialty coffee--must have it at all cost At least one cruise per year is a cheaper five day--it's enough to get a winter fix.
We are in spa balconies this time, but that's because we had to wait so late to book the Splendor (vacation schedules) that we didn't have much other choice besides bad locations and interior rooms, and it's important to us to be close together. Next cruise, we'll be back to our usual cheaper cabins. Our normal big splurge is a cove balcony, which isn't much more than OV, but it's our very favorite cabin type and quite a bit cheaper than a regular balcony.
