Restrooms

I might be going on a cruise with an elderly relative. One of the ports will be Cartagena and i am sure I will be in charge of finding the closest bathroom if they need one. I have been reading the posts and see that there is one at the port and one at the gold museum. Are there any others that you can think of?

I am thinking of marking on a map any hotels we might pass and if they need a bathroom I can buy a drink for them at the hotel and have them use the restroom then. Just want to be prepared. Thanks.

If you take a tour, the tour guide will know which stops have public bathrooms.

All of the shops that deal with tourists have bathrooms and most will let you use them if you ask nicely.

Thank you for the information. Some people have suggested offering a dollar

to use the bathroom in some ports. I am OK with this but just wanted to know in advance so I don't make a mistake in etiquette. Thanks.
