Perhaps starting to show its age among newer and flashier counterparts, Hard Rock Hotel & Casino can still be a decent off the Strip spot.
To that point - if you want to be close to the strip, then stay on the strip. HRH is not on the strip (about a 15-20 min walk) and the shuttles don't run that often. For a R&R solo trip, I chose the HRH because I got a good midweek deal and didn't have much need to hang out every moment on the strip. All up, I had a pretty enjoyable experience here. I had a pretty much hassle free check-in and check-out experience and every single staff member was friendly and helpful. The room was huge especially for just myself and major pluses for the plush and comfy bed. I slept so well every night. My room had zero view but the hotel probably doesn't have a view of much anyway unless you're staying in the new HRH Towers. The pools are adequate but definitely show their age plus they fill up by Noon so get there early. Decent dining selection but perhaps not the most exciting and diverse by Vegas standards. The casino has a decent selection of slots and never felt too crowded or smokey.
For what I was looking for, the HRH & Casino did its job well. I got a comfortable and relaxing stay and a chance to explore more off-Strip destinations. Totally worth it if you score a deal online.
