I won’t even say anything about the park, it’s something you need to experience and you’ll be convinced just by looking at any photos. This isn’t a campground but backcountry camping with a hike to the site of under a mile, so it’s perfect for backpacking trips for families. BUT walking on sand is a lot more tiring than you think it’ll be and water is heavier than you think it’s be!! You need to get a permit, which is very cheap, and forces you check in with the rangers about weather and whatever other issues there may be. Read up about leave no trace and specific rules for the sand dunes. ...the weird thing is that there could be missles on the sand sometimes!! So if you see something weird stay away and tell the rangers asap!! This will be one of the best camping trips you’ll ever be on, no contest. ENJOY!
