Then we climbed the spiral staircase. When we got to the top, we understood.
There are no pews, no gilded crosses, no side chambers. Such items would be unnecessary impediments because this chapel is dedicated to the glory of stained glass. Glorious color surrounds you as you turn in awe to see the biblical stories depicted in the panes reaching from floor to soaring ceiling.
The view from the Batobus is as close as we're going to get to the Eiffel Tower on this trip. It's a shame I didn't follow my own advice. There's a wonderful website where you can buy tickets in advance, but you evidently need to do so more than two weeks in advance. Don't make our mistake. Take advantage of this new service (The Tower is NOT included in the Paris Museum Pass.), and get your tickets early.
Be sure to ask for carafe d'eau (ka RAFF dough) if you want a free carafe of water and two glasses.
No tickets are sold for Saint Chapelle from 1:00 -2:00 (1300-1400 hours).
The Batobus is the marine equivalent of the hop on/hop off tourist bus in many cities. Tickets are €16 for one full day and you can access as many of the eight stops (for example, the Eiffel Tower, Notre Dame, St. Germain de Pres with the "locks" bridge) as you like. The price is €18 for two consecutive days.
