If you'd like to plan a totally private fishing expedition, a snorkel or diving adventure on the magnificent reefs or a relaxing, self-paced sightseeing tour, renting a luxury yacht may be the way to do it. 

You can find companies to accommodate your needs with yachts of various sizes and tons of amenities, including surround-sound stereo, galleys, full bedrooms, baths and showers, all the equipment you need to fish, dive, snorkel or just float around when you drop anchor. 

Some rental places around Cancun include: Yachts E and  Cancun Vista.
