I yelped ahead of time and got some good tips. Since we were bringing the kids with us to Vegas (I know, I know...but my grandmother was going to be in town & we haven't seen her in over a year), we needed a kid-friendly hotel (i.e. space and a fridge).
I ordered groceries from Von's that literally arrived when we did. I didn't want to have to mess with dishes being delivered. So, I just included plastic/paper bowls, cups, spoons, towels, etc with the groceries.
They held our groceries in their cooler until we got up to our room & then brought them right up. When checking in, they scheduled our linen delivery for the sofa bed. The sofa bed was NOT comfy. Glad the kids slept in it and not me!
On day 2, the cleaning lady did a crappy job. Didn't leave washclothes, didn't pull the trash, didn't leave coffee, etc. The other days were fine.
We didn't have any time issues with valet...even the time we left our ticket in the room. Tipping got a bit annoying (especially since we were getting the car out 2 times a day).
We had a beautiful view of Bellagio's fountains! I didn't realize we could walk to Bellagio through the doors at the far end (around the corner) of the lobby until the last night.
The Bosch washer and dryer were a lifesaver! Though small, they got the job done. Just watch the dryer b/c it'll think your load is dry when it isn't.
We got a good "name your own price" deal on priceline & upgraded to the full-sized refrigerator room once we got there (for an extra $40 a night).
I'd stay there again, especially if we have kids in tow.
