I posted before about being in Amsterdam for 10 days - 5 of which are for a conference, bringing our 13 year old. The conference is near Bijlmer Centrum. I originally booked a hotel right near the event, but have been looking at other options. Lodging in Amsterdam is pretty expensive in June, with few options for family rooms or apartments. However, I just reserved a family room at Inntel Utrecht, very close to the train station there.
We have been to Amsterdam before, twice staying in near Centrum and once in Haarlem. I enjoyed Haarlem quite a bit. Is Utrecht similar? The train from Utrecht to the conference takes about 20 minutes, so direct and reasonable amount of time. We added 2 days before the conference and 2 days after for exploring. If it were you, would you base in Southeast AMS (Zuidoost) or Utrecht?
Also, are there metro passes that would save money for commuting on the trains from Utrecht? Trying to weigh in additional transportation costs as factors. Thanks!
