Could you please advise what is the earliest time you can check-in? Thanks
It all depends on your membership level. My best advice is to sign up to the hotel chains (Free) loyalty program, Global Hotel Alliance (GHA is the parent company) before making a hotel booking. Check-in can be from 9AM and Check-out as late as 6PM, depending on your membership level.
