We were there for a week recently. We arrived from Manchester Airport just before Brexit Day and left the week after Brexit Day. Honestly saw no Brexit related change whatsoever anywhere. The only real thing I noticed was a forlorn acceptance of the situation as 11 pm occurred whilst in The American Indian Cafe in PDC on Brexit night. Things might change, slowly, as the transition period this year progresses.
As an aside, and as someone who wants to move to Lanza in the future, we asked an estate agent their thoughts. She thought that the residency rule of only being allowed 90 days in every 180 days might ultimately be relaxed, rather than enforced.
