We are from Essex, UK. Have a 2 day transit visa for Celebrity Millenium in February 14th&15th February, some posts on t/a / internet say transit visit ok, others say needs to be a 30 day transit visa in Sri Lanka? Will be applying for a 30 night transit evisa for India, which now costs a lot less than 5 years ago, any comments re the Sri Lanka one? ps: our US friends have been informed that a transit visa will suffice for this trip?
