Hi - there are 8 of us (4 adults and 4 kids, all teenagers). We are planning a vacation to London/Paris for 10-11 days during Christmas. We will fly into London and fly out of Paris. We've been to both cities in the summer before but this will be our first time during winter break.
Would love to hear your opinion on the general itinerary:
3 nights in London
2 nights in Paris - Christmas eve and Christmas day
2 nights in Strasbourg, should we do Colmar too? (Christmas Markets)
3-4 nights back in Paris
Does this look reasonable?
