United Frequent Flyer miles... best use for Europe (?) travel in May?

Thanks. Holiday Inn looks nice. To this point we have not looked on the other side of the river. Definitely S-Bahn access is a plus. However " max 2 adults plus 2 children" I think means we’d need 2 rooms for our family with grown children. In some ways I like the idea of 2 rooms, but so far not wanting to splurge 145eurox2 per night unless in the ideal location.

Tell me more about that location though. I’ve ruled out some nice and less costly options there.
