Well, here is a summary of preparations so far:
I booked a night in the patron housing at the London Temple for May 6. May 7 and 8 we are staying in a hostel near Kings Cross in London. We will fly from Shannon to Gatwick on the 6th, attend the temple that afternoon/evening. the next morning we will go into London proper for 2 days. I do plan on going to Gillwell Field for the scouters out there. '
Early morning on the 9th we catch the Eurostar train to Paris. it travels under the english channel at 100 mph. We spend the day in Paris and catch a sleeper train that evening to Madrid.
Spain is still flexible with Toledo, Madera, Cacres, Salamanca and other places to be visited before returning to Madrid for the last2-3 days in madrid.
