For those of you wondering whether to book a Solo Traveller holiday with Riviera, my advice is definitely "Do It"! I've just returned from the Berlin and Dresden holiday and it was amazing. I enjoyed it so much that I didn't want it to end. There were 26 people in our group and we all felt comfortable with each other straight away. The hotels were beautiful and we all had proper double rooms - none of those awful single rooms that I'm sure we've all experienced at some time. Everything was arranged very well by Riviera and we were taken care of at all times. I've made two lovely new friends as well which is a bonus.
I already have two river cruises booked with Riviera - one in just a couple of weeks with a friend, but one next year on my own. I'm definitely going to be booking another Solo Traveller tour. I'm thinking about Classical Spain.
