Sounds good Steve
I would like to pay a visit to the Castle at Nurburg.

That wouldn't take too long.
So how does this sound so far?
1: Leave hotel 10.00am (latest) - Nurburg Castle. 30 min journey max. 30 mins looking round and some photos (it's not massive)
2: Leave Nurburg Castle 11.00am ish, head towards boppard (maybe via Cochem) 45mins. So arrival at arround 12.30 ish, lunch and a beer or 2.
3: Leave Boppard at 2.00pm and head to ??????
Remember we need to be leaving the hotel at approx 6.30pm to go to the Tiergarten.
