I managed to snag 1 wk of vacation time in August at the last minute so i'm researching award trips to Europe since cash fares are too expensive. So far only place I see availability is Amsterdam (which is great because i've always wanted to visit) on UA leaving 8/5 and returning 8/9 in business. This only gives me really only 3 days on the ground for sightseeing. Unfortunately I can't request more vacation this summer so I don't have other dates to play around with. Would his trip be a waste of miles for that short amount of time? Is 3 days really enough?
