Hi,
How did your experience turn out? A couple of the travelers in my group will be in the same scenario- They have a multi-entry Schengen visa but no UK visa due to time constraints for their cruise in 10 days. Can they embark and just stay on board during the UK stop? (Schengen Visa, USA permanent resident/green card but Cambodian passport)
We have a back up plan if they are not able to board- with our itinerary, the UK stop is the first so they may be able to embark on Day 1 but on Day 3 when it stops at the next Schengen country (sea day Day 2)
Thank you!
