This might be a little late but for anyone coming from out of town that needs information about SLC, where to find a good meal, the parking situation at and around the Marriott (the Marriott is $12 for the day, you can park across the street at the Convention Center, there is some off street parking but right now there is a lot of construction near the hotel - hope it won't be too noisy - so the on street parking might be a bit iffy - but it's SLC on a Saturday - City parking is free on Saturday's but I have been ticketed for exceeding time limits within the downtown zone (I was visiting several stores that were several blocks apart but I had been in the downtown zone for over two hours so I was ticketed - arrrgh!)), etc., - please feel free to PM me.
I live two miles from the hotel and I have a pretty good sense of where you can get a good meal (not so up on where to get a drink!) and other services you might need. I'll be at the providers conference but I don't expect to make it through the entire day. Lastly, please feel free to PM me if you find yourself in a bind you need assistance - let's hope that's not needed!
If you just want to get spend a bit of time at a nice neighborhood street fair, the Avenues Community is hosting their annual fair a mile and a half from hotel. The fair goes until 6 pm, it can be warm/sunny (Saturday projected sunny with a high of a dry 78). There fair involves some walking, crowds, live music, arts and crafts and food. It is located between I Street and N Street on 7th Avenue (700 east to 900 east on approx 350 North). Park on 7th avenue unless you are OK with walking some hills. It could be stressful - I'm not sure I'd be up for it but it was fun when I was healthy. Healthy relative and partners might enjoy the festival while patients are recovering in their rooms.
Hope you have a good experience while you're here.
