I've read the same about south tower rooms, so it might be worth a tip to get there. I will say though, that I stayed there last summer in a north tower room and had no problems. I was on the fifth floor, but about halfway down the hall, so noise wasn''t a problem. The north tower elevator drops you into the casino about 30 seconds away from Fremont if that matters. The south tower elevator is just off of the checkin desk away from, but close to the casino. It is also convenient to valet drop off, valet pickup and self park. I mention this as drop off and pickup are not the same location. Dropoff is east of checkin and pickup is just west of checkin. At checkin they give you a parking pass you'll need to exit the garage unless you want to pay the daily rate, even though you valeted, so put it in your car the first time you pick up. Kinda quirky. Evidently 4Qs doesn't own the garage.
My room was newly renovated, but a bit small. I was alone so it was no problem, but I would think it would be ok for a couple as well. Magnolia's is a decent cafe. I didn't eat at Hugos, but I've always heard good things about it. The Chicago Brewing Co is great for a nice cocktail. Drink portions are huge and prices are small. I was charged $4.50 for a Dewars Scotch on the rocks, which was easily more than a double. I like to have a couple before dinner, so I went back the next day and ordered while played VP. Same portion (with a different bartender) and the comp receipt was the same $4.50! A single most places in LV is at least $7.00 on up, so it's frugal place to imbibe.
Beyond that, you're right in the middle of everything. Enjoy your trip.
Good Luck!
