You could try checking out the toilets before you need to use one. Wash your hands or blow your nose when you go in there instead of peeing. If you cannot pee standing up in a cubicle because there's a gap under the partition, try sitting on the toilet as the body can relax better this way sometimes. You could try wearing leakage pads which are available at chemists such as Boots and on prescription at the discretion of a district nurse. If you are room sharing at your hotel try putting the tv on as soon as you are in the room and turn the volume to a tidy volume. When you need the toilet your room mate will not be able to hear you then and will also be distracted.
