How to follow up with hook-up from festival

Hi,
On Saturday I hooked up with a really cute that lives about an hour from me. We had great sex on the beach. Saw her the next day, yesterday, at the beach party during the day. We said hi, kissed a bit, although she then hung out with her friends.
She came over later again, we kissed for a few minutes, but then said our goodbyes. When she actually left we blew each other a kiss.

How should I go about the follow-up here? I'm going on a holiday on Wednesday. Just want to avoid coming off as needy.

Thanks for any suggestions.
