As with the majority of downtown / Fremont hotels, this place has some great deals on hotel rooms. I've also stayed at Fitzgerald's and they're pretty much the same, save that Binion's has quicker elevators.
The room was a bit worn, but for a place to keep your stuff and sleep off the previous night, it's perfectly acceptable. Do not expect luxury or any extra amenities when staying here in a regular room at a discount rate.
Downtown is all about some of the last remaining old Vegas vibe, and convenience - there's no way you could visit 6 or 8 separate casinos and a few bars in one night on the strip, without taking many taxicab rides - - but downtown, it's all in walking distance. It's not glitzy, it's not luxury, no floor shows or roller-coasters, just gambling, drinking, people-watching, the Fremont light shows, and regular people generally having a great time.
If you want to stay downtown but step it up a star rating or two, check out the Golden Nugget, and their new pool area.
While the hotel itself was just the basics, I can say that the staff at Binion's were very gracious, helpful and friendly. The coffee shop downstairs is a bonus if you like breakfast any time of day.
They do offer free parking, but it's at one of the two hotel sides (and your room might be on the other side, so prepare for a bit of a walk). I thought I read that they had wi-fi, but couldn't get any sort of signal in my room.
I didn't check out the pool area, so I don't have an opinion on that.
I would recommend this hotel to someone who didn't want any extra frills.
If you're driving to this hotel (or any downtown hotel) from the airport, I suggest driving up the interstate and taking the 2nd downtown exit, as opposed to driving all the way up the strip... The strip will almost always be jammed with traffic, and unless you arrive at rush hour or happen upon an accident, taking the interstate can save you an hour or more in getting to / from the hotel.
