We hear Vidya Balan has booked a Caribbean cruise in December that will stretch for nearly 15 to 18 days. Joining her on this voyage will be her parents, her sister Priya, brother-in-law Kedar and their twins Ira and Ruhaan . For some reason though, Vidya's long-standing boyfriend Siddharth Roy Kapur is not expected to be part of the group.

A friend of Vidya told us, "She would have completed Rajkumar Gupta's Ghanchakkar co-starring Emraan Hashmi by then." Apparently, Vidya had been planning a family vacation ever since her sister Priya delivered on August 15 last year. "The idea of going on a cruise was Vidya's brainchild. She quite loves the sea," said her friend.

Meanwhile, if the grapevine is to be believed, Vidya will tie the knot with Siddharth in December this year. The actress has been in a steady relationship with the UTV CEO for a while now... So where do Vidya's travel plans leave the shaadi?
