As long as you're physically able to walk a couple of miles, it won't be bad. In fact, if you do it in segments, it won't be tough at all.
From Bally's, head east to Koval and Flamingo. Just south of the corner is EI, your first "rest stop." The next leg has you heading east on Flamingo again. About halfway to Terribles is Tuscany, which you can use as another rest stop if you want. In fact, even if you don't want a break, stop in anyway. Another quarter of a mile or so east and you're at Terribles. After some time at Terribles, cross the street and go south on Paradise about a half mile and you're at the HR. Assuming you're not pounding down cocktails at each stop, you should be fine.
Good Luck!
