• Royal Caribbean's Icon of the Seas could be an expensive vacation compared to other cruise ships.
• Sailing on the mega-ship without paying for any of its upcharged amenities is possible.

A budget vacation on Royal Caribbean's new wildly popular Icon of the Seas is possible. Just be prepared to stay sober, repeat meals, and pay at least $265 a day.

Right now, there's likely no better example of the mass-market cruise industry's shift toward the budget airline strategy — charge a cheap base fare and offer irresistible up-charged amenities — than Royal Caribbean's new world's largest cruise liner.

After all, what other ship comes with a $100,000-a-week cabin and a $200-per-person restaurant?

But it is possible to vacation on the mega-ship without giving into any of its upcharged restaurants and activities. If you're strong enough to do so, here's what your seven nights on Icon of the Seas could look like.

Be warned: It won't include lobsters or private lounges.
