(CNN) - Among President Obama's first activities on Martha's Vineyard: a friendly tennis match against wife Michelle.
White House spokesman Bill Burton told reporters Monday on the Massachusetts island the first couple squared off earlier this morning, though it remains a secret who won.
Burton also revealed Obama is set to play golf later in the day with South Carolina Rep. James Clyburn, UBS CEO and major Obama supporter Robert Wolf, and White House aide Marvin Nicholson.
As for the rest of the week, Burton offered few details, saying the president himself doesn't even have a particular schedule.
"He's on vacation, so everything is a little bit loose," he said.
Burton, however, did dispel reports the president is planning on visiting ailing Sen. Ted Kennedy in nearby Hyannis Port.
"I heard some reports today that the Secret Service had visited Hyannis Port. I don't think that there's any reason to believe that there's any plan to go to Hyannis Port at this point," he said. "I think that if Secret Service agents were there, they probably heard like all of you already know, that they have great lobster rolls out there."
Burton also said it's unlikely Obama will spend much time mingling with residents of the 23-mile long island.
"His desire on Martha's Vineyard is to get a little break," he said. "He certainly appreciates the hospitality of the folks who are here, but his desire here is to relax and spend time with the family."
