I do think that Mandalay is a hotel that does check off a lot of boxes. It's got a nice size casino, has a great pool, accommodations are nice, has some decent dining options, location is "eh"--but it does have a free tram that runs to the Luxor and to the Excalibur. If you take it to the Excalibur--you are a pedestrian Bridge away from the New York New York and the MGM. My only concern with the Mandalay is in regards to you mentioning that you have a large group with very wide interests. Trying to coordinate Vegas with a large group can be an exhausting task---I know this with lots of experience. My advice would be to not "over-schedule" things. I would maybe try to plan or co-ordinate no more than 2 activities per day to try to get the entire group to do. For example--I'd tell my group--we'll be having breakfast at "x" location at "Y" time--so be there. At breakfast I'd say we'll be going to Hakkasan tonight at "Z" time--so be there--and let everybody do whatever the heck they want in between. There is regular time--and there is "vegas time"--and vegas time generally involves things taking much longer than anticipated. The minute you try to fill an entire day with activities with a large group in vegas--you will start to fail. I have to tell you that in my experience with large groups--I actually prefer to stay in more of the "timeshare" style resorts--and stick with 2 bedroom units (as you get 2 bedrooms and 2 bathrooms). The rooms are laid out more like apartments with living rooms and kitchens--so they are perfect to throw your own in between activity drinking parties. You go to a grocery store--buy alcohol by the bottle at cheap prices, get a 24pack of water, get snacks--and that way your entire group is not gouged by the crazy prices of the typical strip hotels. One of my favorite timeshare style hotels to stay at is the Grand Chateau by the Marriott. It's literally a quarter block off the strip and is directly across the street from the Planet Hollywood. I also love the Hilton Grand Vacations club at the Flamingo Hilton. It is located on the back end of the flamingo hilton property--which is mid-strip--and it steps away from the monorail location--which makes navigating the strip soooo cheap and easy.
