Hi Ian!
Welcome to planDisney!
I always enjoy visiting Disney's Yacht Club Resort for breakfast or dinner and it is in a really great location as you know, within easy walking distance of EPCOT's International Gateway entrance. Using
Disney's Skyliner would be the best way to travel from your Disney Resort hotel -
Disney's POP Century Resort to EPCOT - but the Skyliner (and other
Disney transport) will only begin operating around an hour before park opening. On this occasion I think you will need to take a taxi - just stop by the Front Desk of your hotel and ask them to call one for you.
After your breakfast, please take some time to stroll over to Disney's BoardWalk - maybe leave some room for an extra coffee while you sit and enjoy the view, before heading into EPCOT for the day, or taking Disney's Skyliner back to your hotel, which should be running by that time! This is like an attraction all of its own, with a wonderful view across Walt Disney World as you travel along.
As you are visiting in December (so soon!! so exciting!) you can also enjoy all the beautiful Christmas decorations, everywhere - at the Resort hotels, the theme parks and Disney Springs. The
Disney Parks Blog gives you a taste of what you can expect. I would so love to be there too!!
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical vacation!
