Well being in PE, your access is not certain
You could:
1. Check the Itinerary section on V-Flyer to see if anyone is travelling on that day and offering access (denoted by L)
2 . Attempt to pay for entry (£60 per person), but this is subject to availability
By saying "nails done" I assume a paint job ): That is between £17 - £30
