Agree with all above. I can't imagine any hotel around Wrigley being safe, usually hotels uptown are "shady" at best. I'm guessing if you get a room downtown, parking will be included but I can't say that for sure.
You will want to be as close to the redline as possible - that's the train that will take you right to Wrigley (Addison stop), so when you shop around for hotels get accurate distances from redline - they will probably all say "within walking distance" but you don't want to be 8 blocks from the redline if you're going in and out a lot (8 city blocks is 1 mile, fyi). I live just a tad north of Wrigley and I work downtown so let me know if I can help in any other way.
If you plan on going out for steak - I recommend Gibson's steakhouse - it is the best steakhouse I have ever been to, a little pricey but worth it. I also recommend trying to go to the Shedd Aquarium but buy your tickets online before going because the line is huge if you just go there to purchase. If you buy online prior you get to stroll right in and laugh at all the suckers waiting in line!! Good luck and have a blast!!
