There's a reason we look south for great value for summer travel -- all the warm-weather deals. The Westin Grand Cayman Seven Mile Beach Resort and Spa is just one example, with a fun special offer on tap.

First up is the Pay Your Birth Year promotion, where you can finally feel better about older age. For select nights through the end of the year, pay rates from $259 on your first night, then pay your birth year plus $100 for the second and third nights. So if you were born in 1960, you would pay $160 for additional nights.) Use promotional code BIRTHYR -- and don't forget to bring your ID, which is required at check-in.

Here's when we found availability for the promotion: May 7-16, August 20-31, and all of September and October, with the exception of Halloween. If you can swing it, it’s worth waiting until late summer to check in. Rates for the first night in May are $299 for a king bed with an island view, while they start from $259 in late August through October.

There's also the Vacation Bonus special, which gets you a fifth night free, $100 resort credit, and excursion discounts ($30-$35 off) through December 19. Use promotional code ZS5. Another deal of interest is one that slashes every second night by 40 percent when arriving Thursday through Saturday; book using promo code ZB4.

More about the hotel: As an island resort, the property is surrounded by pristine sand and turquoise water. The guestrooms and one- or two-bedroom accommodations offer up views of either the island and ocean or the pool. When relaxation is in order, slip away to the Hibiscus Spa, which features steam and sauna rooms, a women’s whirlpool, and 13 treatment rooms.
