Hi!

I'm trying to find out the opening hours during weekends for the Scandinavian Lounge at Arlanda T5.
SAS website isn't really saying much, and I haven't been able to find out by searching this forum either.
I have a number of trips that initiates on Sundays for the upcoming months, and I'm a little bit curious as to whether the Scandinavian or even the Business lounge stays open for Sunday travellers?

The question basically boils down to: Should I book a tight connection at ARN (as my trip doesn't originate there), or should I leave time for a stop at the lounge?
