Spend three nights in Las Vegas with this Delta Vacations (tel. 800/800-1504; package at Red Rock Casino Resort and Spa, from $251 per person with airfare.

Red Rock Casino Resort and Spa, about 15 miles west of the Strip, is the place to indulge in spa treatments such as a green tea wrap and Thai massage. On-site dining options include modern Japanese at Hachi, homemade pasta at Terra Rossa, and more.

Expect June temperatures to be in the upper 80s. But don't sweat it. The hotel has a free shuttle to the Strip.

Why is this a deal? A nonstop Delta flight is $138 from Salt Lake City to Las Vegas. The hotel is offering the third night for free for Delta customers. If you booked the hotel on your own, room rates would cost $150-$175 per night for a deluxe king or a deluxe with two queens ($475.80-$561 for three nights, or $237.50-$280.50 per person). If you bought airfare and hotel separately, you'd pay $372.50-$418.50 per person. Booking the package saves you about $112.50-$158.50 per person -- enough for a spa treatment.
