Coronado, California - California's famed Hotel del Coronado doesn't make it clear whether men can be mermaids too in the promotion of its Mermaids Fitness classes, according to the Association of Mature American Citizens.  But, it might be open to letting the menfolk take a peek as the instructor puts the next class of fitness-minded ladies through their paces in its Beach Village pool. 

The idea is that swimming the way mermaids do, using their fish tails, to propel them through the water is a better way to build core strength.

The aerobic exercise classes don't start until next spring, but the hotel is already taking reservations on its Web site.  It costs $25 a session and that includes your mermaid tail rental, although it'll cost you only $10 per 45-minute workout if you bring your own tails.
