ROOM
I have ALWAYS stayed at the Golden Nugget downtown and LOVED it. They frequently have good deals on rooms. We have stayed there with an upgraded room with a coupon book AND free tickets to their house show (Gordie Brown) and the room rate was around $40/night. Yes, I said $40. You may think, "eww, what kind of No-tell Motel is that?" but I swear it isnt. It is a really nice place. I absolutely love walking around down there at night with a cold drink in one hand and some unhealthy snack from Mermaids in the other and watching the Fremont Street Experience. It isn't as wild to me as the Strip.
FOOD
---Mermaids downtown has a snack bar in the back. THe casino may not be the best to look at, but the snack bar has great unhealthy bar food like fried oreos, the big fat green hot dog, chocolate covered frozen bananas, etc
---DuPar's at Golden Gate downtown has the BEST shrimp cocktail ever. Last time I was there I wanted a slice of apple pie and they asked if I wanted cheese on it. I thought I was losing my mind, but the waitress explained it was the new thing--apple pie with a slice of sharp cheddar melted on top. I tried it and it was aMAZing. You taste the nuttiness of the cheese mixed with the apples.
---The dinner buffet at Paris is my absolute favorite. Crepes, duck, best gouda cheese ever, prime rib, etc etc.
---Mr. Lucky's 24/7 at the Hard Rock Casino (it is NOT walking distance from the strip)....NOT the Hard Rock Cafe, it is INSIDE the casino. Ask for the Gambler's special. It's a steak, 3 shrimp, potato, carrots and was sooo yummy.
---Serendipity 3 down by Caesar's on the Strip. People go there for the frozen hot chocolate which is AMAZING on a hot day. We also got a burger and buffalo strips to share and those were good too.
---I will try to remember where that Hangover Burger is from. I KNOW it is downtown, but I can't remember the casino name off the top of my head. It's a tiny dive looking cafe in the middle.
Stuff to Do
-do the touristy stuff...Bellagio fountains (free), Mirage volcano (free), Eiffel Tower elevator ride (not free), Madame Tussaud's Wax Museum (not free)
-See the Mob Museum (not free) it will help you learn the history of Vegas
-See the garden/floral exhibit at the Bellagio and the Chihuly ceiling
-Take in a show (I wish you could see Phantom at the Venetian, but it closed
-if you drink, be a fool and get one of the tacky souvenir glasses...(guitar, football, Margaritaville pitcher, chalice, etc)
-see the lights at night and the Vegas sign
-go to Bonanza and see all the CRAZY souvenirs and gifts
-DO NOT TAKE CARDS FROM THE SMUT PEDDLERS ON THE STREET (however, to shock my grandmothers I DID buy a shirt like they wear at Bonanza that says something about live girls direct to you and has a sillhoutte of an exotic dancer)
-be sure to get you the discount/coupon books. I usually find them in the taxi I know one is called What's On and you can also find it online. I had 2 for 1 ticket coupon for the Eiffel Tower from there.
TIPS
-If you are not used to the dry climate, be sure to take lots of water, lotion and chapstick.
-like with Disney, there is a LOT of walking involved here if you plan to walk all of the strip and downtown
-if you see food or drink that looks interesting, TRY it
-if you see a neat attraction, DO it
-you dont have to spend all day gambling
