One question I didn't find informations about, but was always an issue at these events, are there any food options which are open late at night or even 24/7? I look at Max and McDonalds so far and they seem to be closed at 0 am and not open till 9am. (Only in the city one McDonalds is open till 4am on Friday and Saturday)

2.5km to the mass housing and 3.3km to the hotel is still quite a bit, I would normally be ok with that too, but keep in mind not only heavy luggage, but it could also rain.

Sorry, I thought that was more clear. The only thing I couldn't find out, if you could also take the bus, when you have a non-öresundtåg train. The webside of the local traffic organisation wasn't really helpful.

So the only reference on the local transport is this in swedish: http://www.lanstrafikenkron.se/enkelbiljett "Enkelbiljett för tågresa medger gratis resa på buss i ankomstzonen. Enkelbiljett för tågresa köps med fördel före ombordstigning." "One-trip ticket includes free travel with bus in the arriving zone..." I look on SJ if there is another reference.

Here also the swedish link for reference: http://oresundstag.se/information/biljettgiltighet/

"Traveling Within City Zone Your ticket for Öresundståg is also valid for the public transport within the city zone that you are traveling from and to. The ticket is valid for one connecting trip within one hour before the train's departure time and one hour after it's arrival time. For more information about traveling within the city zone, please contact the regional public transport company that you will be traveling with. When traveling to or from Copenhagen, your ticket is valid in zones F + L (also called 1, 3 and 4)." And if you are traveling from Copenhagen: "A ticket with departure station within zones F + L – e.g. Copenhagen Central Station or CPH Airport – is valid for any Öresundståg on the same line within three hours prior to and three hours after the specified departure. No re-booking is required. Seat reservations do not carry over."
