Hello friend greetings to you. Hope are having good time there.

The backbag is the best option. I like it personally. The reason is because rucksack is very easy to carry and even it looks good too.

You said the luggage if personal hygiene is important. I do think so. I am really discomfortable in place if I feel their is dirtiness or things like that.

I wish you very best of luck here in the contest.
