Something that's extra fancy or of very high quality is deluxe. If you upgrade to a deluxe hotel room, it will be bigger, more luxurious, and probably have a great view.

You're most likely to find deluxe describing a spa, hotel, car, or house. When any of these things is deluxe, it goes beyond the ordinary to provide a superior, luxurious experience. A deluxe home might have thousands of square feet and an in-ground pool, and a deluxe cruise probably includes a large berth and gourmet food. Deluxe comes from the French de luxe, "of luxury," from the Latin luxe, "excess or abundance."
