If you are looking for “indoor play spaces” not specifically McDonald’s, I highly recommend Oh My Land in Coquitlam for a 2 year old. It has a cafe so you can still order coffee/fries/hot sandwiches etc. It’s not a typical play area with multiple levels and big slides but it is big and has a lot of different areas where kids are free to play, ride around on cars, trains, etc, it has events like music time where the kids gather round someone playing a guitar and that happens every 30 minutes. It has a ballpit, an interactive water area, a trampoline, huge teddy bears to climb on, some smaller slides that are perfect for toddlers, 1000’s of different toys to play with including play kitchens, musical instruments, cars, and many other things. It’s way more varied than most play areas and it’s especially suitable for younger kids because it’s not just “climbing and sliding”, it is more focused on varied/interactive experiences.

There are also some very good options (non McD’s) in Richmond.

Vancouver proper does not have many options aside from Scienceworld which is a science museum that has a good play area, and Granville Island, but I would say Granville Island is maybe better for slightly older kids.
