Staying at hostel vs staying with parents?

Hotel not hostel

depends on your relationship with your parents. If you get along well, stay with parents. If you don't, then stay elsewhere to avoid stirring up old problems. If the visit is for more than a few days, then you need to ask them if you'd be in their way. Get an honest answer. In any case, ask them if you can stay with them--don't just show up.
