Driving up from san diego to meet friends in vegas. Trip is a combo of Hubby's Bday and our 6 year anniversary. Staying 3-4 nights between May 18-24, dates flexible. We love the pool and suites at Mandalay bay, but want to try one of the new/renovated hotels. Who's offering the best value added package that week? We like the look of the monte carlo pool, can you access the other city center pools if you stay there?
