The first time I stayed in Vegas I stayed at Caesar's Palace. The rooms were bright and sunny and the pool was full of hottness. The beds were super comfy and the location was clutch.
Of course, the expenses that weekend were covered by work.
Our most recent friendcation was on our individual dimes and we decided to book a room at the Flamingo. It's the perfect spot to cut lodging costs so you have more expendible income for booze and the blackjack tables. We were given a "junior suite" (non-updated) that was massive and plenty of room for the 4 of us (we could have easily slept 8-10). The pool was great, too. Lots of people everywhere, friendly bartenders, and just enough sun to get a tan. They could have more bathrooms, though.
The only bad part of the stay was the broken ice machine outside of our room. We needed ice... to keep our drinks cold in the room, and the other ice machine was at least 1/2 mile away down the hallway (oh yeah... you could drop 10lbs just walking from the front entrace to your room depending on what wing of the hotel you are staying in).
The location is awesome and the hotel met our expectations. Also, the food court in the casino was perfect for morning, mid-day, and late night eats. Great experience and I'll definitely be back!
