I found the following information on Gdansk Poland tours at toursinpoland.com It would be nice if we could get 8 people together.
GDANSK, OLIWA, SOPOT, GDYNIA - by car
Time: up to 6 hours
Price: EURO 300 /max 4 pax/
EURO 400 /max 8 pax/
EURO 700 /max 20 pax/
over 20 pax - prices negotiable
The tour includes all historical high-lights of OLD TOWN - see Tour No 1.
After visit to Old Town you will visit SOLIDARITY SQUARE, located close to the famous GDANSK SHIPYARD and then OLIVA CATHEDRAL, where you will be enjoying a short ORGAN RECITLE.
We will go to GDYNIA next, to see the port and then back to SOPOT - famous Polish spa at the Baltic coast , where you can have a walk in the LONGEST WOODEN PIER in Europe.
There is always some place in Sopot when you can end up with tastefull lunch/dinner in local taverna.
