in the early morning for breakfast. I noticed in pictures that the lounge does not look very big. we will prob be in there the hour before the parks open
The lounge is actually the largest concierge lounge we've had the privilege of utilizing while at WDW. I can't speak to GF, AKL, or Contemp though.
There is a good bit of seating in the lounge area and we've never had a problem getting a place to sit. Now, you may not get one of those coveted "window" tables--but you can see across the lagoon from anywhere in the lounge.
Our vacations are during the summer (mid-late June) and the crowds are fairly large. If you are going soon, you shouldn't have too much trouble. We also are usually in the lounge around 7:00 a.m. A good many people take trays back to their rooms--when our kids were younger, we did too--it was just more convenient to send one parent after food for all while the others were getting ready for the day.
We are usually there 4th of July week and we get breakfast before the parks open and have always found a table. There is also seating upstairs and if that does not work, just grab a tray and go to the room. Some times I liked bringing it back to the room to sit on the patio.
