The pool at the Flamingo Las Vegas.

The much-hyped efforts of Las Vegas to turn itself into a family destination a few years ago pretty much fizzled — there’s still plenty of sin in Sin City — but anyone looking for a pool vacation for the kids this summer might want to consider this desert spot. The pool scenes at any number of hotels (including recent expansions at Mandalay Bay and the Excalibur) are fairly over-the-top, but few can rival the 15-acre “tropical oasis“ at the Flamingo Las Vegas , with four pools, a water slide, several waterfalls and a subterranean grotto that can be explored either on foot or by water. And for the adults, there’s even a swim-up blackjack table. Weekend rates for a room with two queen-size beds (suitable for a family of four).
