We did the FDP the last two trips with BOG dinners prior. The first year we had a 6:00 pm ADR at BOG, and we were way to full at the FDP. We did skip dessert at BOG too. Last year we decided on an early 4:00 dinner at BOG and it worked out perfectly for our family and friends with the FDP. I would suggest an ADR no later than 5 pm.
We are skipping the FDP this year. Although I reserved right away with the first seating time, they assigned us to a back table with little room close to the desserts. I was not happy with how difficult it was to get out of my seat. They put 8 of us at an assigned table, the same size table they had four people at. The first year I booked as soon as the date was available, and we had a great table that was assigned along the railing. They also had the photographers back then so you had a great picture with the castle illuminated behind you.
