My family will be in Lille for eight days in June while attending some Euro Cup games; four games in Lille and two in Lens. While in Lille, we are planning on visiting Arras and some of the WWI Memorials as well as Ghent while setting some time aside to really feel a part of Lille. After leaving Lille, we will be in Belgium for five days; two in Bruges and three in Brussels before flying out. We plan to visit Antwerp while in Brussels. So...long story a bit longer, For two and a half days we have a break in between games are are looking to get out of Lille. We planned on going to London before the price of the train scared me away.,,
We are now considering Rotterdam (we were in Amsterdam two years ago) and Cologne. Both seems to be about a solid three hours from Lille by train. My question to the community, which would be the better venue to visit for two days? Also open to other suggestions so long as they are about three hours by train. Thanks in advance. Regards.
