I was able to pop the canopy up by myself !!! I was so surprised how easy this  was to go up . The side walls I am going to definitely  need a hand to put on as I don't want it to get dirty but it looks really  simple  . As for space under the tent let me tell you  there is plenty of room if you  have a large family or having a gathering I wouldn't hesitate to make this purchase as it's great on space and easy to take up and down
