What exactly is the single supplement?
The published rate of a package is always calculated per person but based on 2 people sharing the same room throughout the stay. Single supplement is an additional cost on top of the package rate that single people who wish to stay in a single room during the duration of the trip would have to pay. E.g. Tour rate is listed as euro 1000, single supplement as euro 200. It means if you are traveling alone on this tour, you pay euro 1200. However, if a friend joins you, you would only have to pay euro 1000. Your friend also pays the same amount.
