Last time to WDW we did just carry-on. It really wasn't a problem. Well, at least not until the flight home!! We sat in the most forward row, 2. There is no overhead storage for that row. So, put our stuff in the bin over row 4. Figure I'm going right past there to disembark. Nope, they decided to have us use the front door!!! But, a nice man grabbed our two bags for us so we didn't have to go backwards, like salmon, swimming upstream.
But, that story aside....I have to say that the one time we flew PanAM out of Worcester Ma., they allowed no carry-on at all. It was about 2 months after 9/11. That flight boarded and took off in record time!!! My flights with Song have been close to that but not quite as quick. I have to agree with Gail...I hate feeling like a packmule. We'll probably be waiting at the baggage wheel of fortune this August as well.
