The Bellagio is my home away from home when I am in Vegas and I like the Bellagio Suites much better but the first time I ever traveled to Vegas I stayed in a Bellagio deluxe room. The deluxe room is very nice - nothing fancy or spectacular, but very clean and spacious. You can see photos of the rooms on the Bellagio website. It is true that the deluxe rooms have not been updated (about three years ago they renovated all of the suites but not the standard rooms) but they are just fine. The location coupled with the vibe of the hotel itself are the primary selling points, as is the fact that being senior citizens, your mother and sister would feel more secure because you must show a key to security to gain access to the guest elevators. If a lakeview is available it will be an extra $50 per night so you may not want to go that route - instead, request a pool and garden view, which overlooks the pool area and City Center and is my second favorite view to Lakeview. The pool area at Bellagio is one of the most beautiful in Vegas and has more of an adult feel to it, as does the entire hotel in general. The $100 in Freeplay and two free buffets alone put this deal over the Mirage any day of the week. Friday and Saturday are the most expensive nights of the week to stay at any hotel so for Bellagio you have been given a spectacular rate. And I would advise them to use those free buffets on the Friday or Saturday evening because that is when they have the gourmet dinner buffet that is normally around $40 a person. If you do make the reservation, be sure to tell the reservationist that you want the MAIN building, and not the Spa Tower. The Spa tower elevators are quite a hike from the main entrance. I admit that I am partial to Bellagio because I love it there so much, but while Mirage is a nice property, it is not even close to Bellagio. For the minimal amount extra that you will be paying for the Bellagio, you will be giving them an experience that they will remember for a long time to come.
