Thanks. I didn't know about that.
You're going to be in the Coast on 105st 101ave? Theres no pedway connecting all the way to that. You'll have a quick walk to the former Bay building and you can walk indoors from there. Some of the pedway is underground, occasionally its an overpass pedway. Its all marked. Alternately your hotel is about a 5 block walk to the Arena. You'll want to walk 104st to see that street and several shops, restos along the way there.
If I was a visitor I would want to hit up the Arena district well before the game, take a look around there at the Marriot, the adjacent Casino, Ford Hall. the whole build is interesting to look at, then head for a dinner before game.
DOSC is a nice restaurant that would be on your way to the game.

It gets really good reviews and versatile menu and the place is conscientious about any dietary restrictions.
I mentioned before that Braven on main floor Marriot is a nice place to go for dinner. After the game you could check out the Alchemy bar which is a really nice spot in the Marriot. The Marriot is the hotel that is attached to arena and that housed the NHL bubble playoffs.
