Yes you can have FOTL access before you check-in (by that I am guessing you mean when your room is ready). Just go ahead and check in as early as you want...they will give you room keys, they won't tell you which room number...you just have to stop by the front desk on your way back and get your room number. They will hold your luggage for you so you can park your car. This is not a problem at all...we have done it many times at the Portofino...should be the same over at HRH since the same company owns them. Have a great trip! FOTL access is excellent!
