This was very valuable for traveling the strip while I stayed at Bally's. Get the 3 day pass and you'll save some money. You'll use it for at least two days while seeing all the sights and can take it down to Fremont street and buy a bus pass for the rest of the way (don't walk it unless you want to stop at shops along the way, it's a good 40minutes by foot from the monorail). The monorail is very clean and runs about every 5-9 minutes, depending on which stop you're waiting at.
