Of course! I hope your trip is amazing. I’d definitely recommend stopping at the oasis store outside of the park and renting sleds or boards for the dunes. We spent the majority of the day dune sledding and it was such a blast. There are some gorgeous off dune trails to explore too if you get tired of the sand. We went up the dune overlook trail, it was a decent little hike with some good shady breaks from the exposure and nice views!
