If you choose an excursion with a long transfer time to the main destination (e.g. Civitavecchia to Rome) it is likely that a convenience stop will be made.
If you choose an excursion that includes refreshments or lunch, there will be toilet facilities available at the refreshment/lunch venue.
We cannot guarantee that there will be toilet facilities on the coaches used for our excursions as we do not know until the day of the tours which coaches will be supplied to us by the local coach operators.
