Looking at the Copenhagen Marriott Hotel on 12-17 May.

The only rate available is "Special Event, prepay in full, non-refundable if cancelled more than 1 day after booking, no changes"

For the cheapest "Guest room, 1 King or 2 Double, City view" Marriott rates are:
DKK 2,699.00
DKK 2,599.00
DKK 2,599.00
DKK 2,699.00
DKK 2,699.00

btw I know the Renaissance Malmų is nearby and less than half the price, but it is not really an option (yet)

All suggestions appreciated, because as others have commented: LNF is not as easy as it used to be...
