Well...it's going to be really hard to convey all we experienced...I'll give you the highlights:
We did this on the Crown in May 2019
Spent a couple of days pre-cruise in London (this was Southampton to FLL)
Did a third party transfer London to Southampton via Stonehenge (International Friends Tours...highly recommend)
Guernsey is very rich in WW2 history
Got to visit the Blarney Stone
Saw many Irish Pubs
Visited "The Dark Hedges"...a filming site for Game of Thrones
Several stops involving Titanic
Liverpool was one of the highlights (for us...group of 8, all Beatles fans!)
Visited Penny Lane, Strawberry Fields
In Scotland...Loch Ness boat trip (did NOT see Nessie...😒)
Inverary castle
Edinburgh Castle
Normandy...probably our biggest highlight! We were there the day before official 75th anniversary of DDAY ceremonies. The place was CRAZY with people from all over Europe who had brought REAL tanks, troop carriers, howitzers...it was AMAZING...and this was not the stuff included in the local WW2 museums.
Very sobering to see the American Cemetery...if you saw Saving Private Ryan you saw this at the very end of the film. Very moving.
I've just scratched the surface giving you the highlights...it's hard to give you a real feel for what you'll experience. It was the trip of a lifetime for us...but we'll probably do it again at some point.
