Yes, actually, we just did a cruise this past December. It was me, DH and our 4 children. We homeschool so we weren't hampered by school and available dates. We sailed on
Royal Caribbean out of Cape Liberty (which we could drive to) on Explorer of the Seas. We did a 12 night to the Southern Caribbean. Everything we priced, even on different lines, the cheapest way to sail was doing 2 connecting interior rooms. They are even cheaper than the family suites. And honestly, we were hardly ever in our rooms. If sailing in a cheaper room allows us to vacation more often, that is the way to go!

If I can answer any questions, feel free to ask!
