We are visiting Paris for the first time for 3 nights in early December and plan to pre-purchase tickets for the Eiffel Tower. Undecided about the best time of day to visit? We are stayng in the Montmarte District and ideally want to combine the Tower with a full day of siteseeing, starting from the hotel at around 10.30am - back to hotel to change and then out to dinner (special birthday evening). It will be a Sunday evening. Any suggestions for itinerary for the day would be great.
