Yes it is and depending how fast you walk and the route you take it’s probably 20 minutes maybe 30. There are two routes on Google Maps and I would go through Waterloo Park. There’s lots of walkers and bicyclists on that route so ask for directions once in the park. The other route is left out the hotel to King Street, turn left and you will come to University Avenue and King Street and that’s WLU at that corner. If the walking is poor because of snow or ice, I’d take this route but on a pleasant day, going through the park is lovely. The hotel staff are lovely do they might have a paper route for you to follow.

You can check in to most Marriott and Hilton hotels by using their respective apps. Of course you then have to be a member of their loyalty programs, but that gives you with many benefits anyway, so why not do that. I always check in via the app. That also gives you the opportunity to setup standard requests like “no smoking room”, “upgrade if possible” etc.

The rooms we have stayed in didn't have microwaves but I'm pretty sure there is one down by the front desk. If not, everyone is so helpful...just ask, they'll help you.
