Very nice day trip to Rotterdam, Delft, and The Hague. Loved seeing the yellow houses in Rotterdam and Delft especially. Our guide, Pete, was very good! Only suggestion would be that it would be nice to rotate seats in the minivan, like they do on guided tour buses, so the same people are not always stuck in the back with limited visibility! And for the guide to be careful of making derogative jokes and remarks against those from certain countries, which is very hurtful to those with family from that country!!
