this is strange, usually a transfer fee is separate and ordered separately. Have no idea what this 'transfer adult fee' with expedia and Hotel Ukraine. I would not.
Adult tickets are for everyone aged 16 years and older, with the exception of NSW/ACT Senior Secondary Students and those eligible for a concession fare.
