Hello
So my family and I lived in Hong Kong for 13 years than we moved away to the Middle East (2.5 years ago) because of my parents work and so the family is going on vacation to Hong Kong for 30 days (Chinese new year ) and during the 30 days we will stay in a hotel also during the 30 days we will need to make make a replacement id for my brother because his 19 years old now and 2 id for my 2 siblings for reaching 11 years old also a replacement id for me because I lost my id. We can stay in HK for 30 days thats the maximum we can do because we will need to go back for schools, work and university. We just check for appointments but it was full also in the form they asked for Hong Kong address.
So what I want to know is
1. Can I go to the immigration office and get an appointment on the same day rather than waiting 25 days?
2.can I use the hotel address for issue/ replacement id card?

Yes Also I want to add we hold a permanent ID card.

Sorry my English is not that good.

Thank you.
