this should be no problem for you. the resort has a sort of gate arrangement at the entrance that you operate with your room card. there is an intercom there to the front desk, she just needs to announce herself as visiting you. if she has your room number it would be helpful. we had the same situation 2 yrs ago. i also went to the desk and got a parking pass for the beach house/palmetto dunes area for my sister.
have a great time!
