Question re ESTA for the US

[Darleydale]

We are going on an Alaska cruise , entering the US from Vancouver Canada and returning to Vancouver.

When the ESTA asks for a US address and point of contact , what do I put on the form. As I am not staying in any accommodation in the US  Other than being on the cruise ship.

Use the address of the RCCL port agent for your first U.S. port of call - do not believe that the address is that important - you only provide an address when you apply for the ESTA - if you at a later date visit US using the same ESTA you are not asked to update the address.

also  get the eTA  for Canada  if you have not done so already
