After lunch at Bofinger, we returned to La Trémoille and only missed our late check-out by 15 minutes, bid our adieus and were on our way to CDG. Sadly, our whirlwind 72 hours in Paris was over. La Trémoille was a pleasant hotel in an absolutely fabulous location (perhaps the best location in Paris we have stayed), but there were enough little annoyances that we are unlikely to return.
With little Saturday traffic, our taxi pulled up to T1 departures level some 25 minutes later. Although we were booked on the 6:55P flight, pleasant LH First agent moved us to the earlier 5:55P flight and got us bulkhead seats. 15 minutes later after a maze of tunnels and walkways, we were at an empty security are for gates 60-68. And a few minutes later in the dungeon that is the *A and LH Lounge. Perhaps one of the most depressing lounges I have seen in a long time.
At some point during our visit, the lounge dragon came over to apologize that due to our flight change, there would not be a meal for us on board. After the "meal" on the inbound, I'd say that this was actually good news.
