Hi all, I will be doing a caribean cruise from the UK starting at Barbados we will be visiting San Juan in the Visa application what do I put in the visiting other countries whilst in transit ? Any help appreciated.

Than you

Even though our Panama Canal cruise started and ended in the US we put all the countries down with commas. Since San Juan is in the middle of the countries you could put that in the middle in brackets/bold writing within the list.

If that makes sense.
