Finnair Flight disruption - Overnight layover support

[yreja]

Hi everyone, My flight is rescheduled to the next day due to disruption. This adds an overnight (24 hours) extra layover at Helsinki to my itinerary. I have accepted the changed proposed by Finnair. I called Finnair to check for the support in Helsinki for the Hotel, etc. They told me that I have to talk to the Finnair support team after reaching Helsinki or book my hotel and claim later on.

What is the best option - to wait till I land to get a hotel voucher or book in advance? I am reaching 4 am in the morning and traveling in economy class.
