Q: i'll arrive around 8pm from taipie and have my connecting flight to winnipeg also around 8am the next day. after passing through custom/immigration procedures and checking in for my next flight, i have the whole night layover. i prefer just staying inside than get a hotel which might be a bit expensive.
A: once inside the secure area you should be able to stay overnight, there is a hotel attached to the airport terminal so you wouldn't have to go looking for one should you decide to spend some money.
