Ready to book a cruise for next year? Think about booking tomorrow or Thursday—September 29 and 30—when Royal Caribbean is having a 2-Day WOW Sale. The sale is good for cruises and cruisetours (its cruise-plus-land-tour packages) that depart after January 1. While it didn't wow us with any deep discounts on sailings, it does include:

• Up to $200 onboard credit
• 50% off your deposit

To boost your savings potential, check out Royal Caribbean’s Hot Deals page, where you can find the lowest available fares, such as a 7-night Mexican Riveria cruise starting at $639 per person for a February sailing. Meanwhile, your onboard credits can be used toward spa treatments, casino games,  shows and more. The line’s new Allure of the Seas and Oasis of the Seas offer kid-friendly water park zones, kid gyms, ice shows, and even character breakfasts featuring familiar faces from Shrek, Madagascar and other DreamWorks movies.

The 50% reduced deposit and onboard credit offer is only  applicable to online bookings. Take note: the online booking confirmation won't reflect your reduced deposit or onboard credit. The WOW Sale Onboard Credit and 50% Reduced Deposit offer is good until September 30, 2010, 11:59 pm, local time.
