Cloack Rooms for travellers passing through HK.

Dear Sir, we are visiting Hk &Macau in Sept.2015. We break journey at HK on 13-09-2015 on our return journey from theUSA at 20-20hrs HK time. After visiting the places we board our flight back to CCU on 18-09-2015 at 10-35hrs flight of Dragon Air. We both are senior citizens &move around with the help of wheel chairs. We wonder if the airport has the facility of a clock room for depositing our four pieces of check-in luggages during the days we visit the places as mentioned above. We would like to know if such a facility is available and if available what will be the charges and whether prior registration for availing of the facility is required. Appreciate your patience and understanding. Regards, Yours Sincerely, Santosh Kumar Talapatra & Mrs.Deblata Talapatra.
