I stayed at the Fremont last summer. Rooms are small, but I was solo so it was fine. It might a little tight for two, especially on the bathroom counter which will not hold two sets toiletries without a platoon system. Other than that a couple might survive if you don't require spacious surroundings, rooms are clean and comfortable.
Avoid rooms on the south end of the tower to eliminate noise. Location is great right in the middle of things. VP is decent at the quarter level and above. Tony Romas runs a prime rib special every night that is good from what I was told. The 2nd St Grille has a killer T-bone special and there is a snack bar for filler food and coffee in the morning. I give mixed reviews to the buffet. Breakfast is fine, I had the Seafood buffet a couple of years ago and was nonplussed. Avoid Steak night at all costs. I asked ahead of time if steaks were cooked by order and was told yes. They are, but they are the thinnest steak I've ever seen in a restaurant. The café in in the same space as the buffet, but I've never eaten there. That's all I've got.
Good Luck!
