Hong Kong Visa - Sponsor Letter

Dear Sir/Madam,

I have already done a Hotel Booking through Agoda.com and my sole intention to travel to Hong Kong is Leisure. I have no relative nor on a business trip, hence unable to get you an invitation letter. Also the Hotel I booked, refused to get the Sponsor Document signed as I have not directly dealt with them but via agoda. They agreed to confirm the booking via an email. Will this be sufficient??

Or else do I actually need to submit a Sponsor Document as I already have a booking confirmation from Agoda.com and I have paid in full for my accommodation there.

Please advise as early as possible.

Kind Regards
Shamali
