Monte Carlo has a great pool area and the tram to Bellagio & that corner is really great. Mandalay Bay is also really enjoyable with their pools & there's a tram to Excalibur. I have a twelve year old that loved Excalibur...up to last year because their pool is big but only 3 feet deep. The Orleans is also good because they have bowling and theatres and nice pool.... Good luck. Steve B
