I'll ask tomorrow , purely a guess but i'd guess they won't because there going to be serving food on board.
Other things in the area that may be worth a look are :
http://www.tropiquaria.co.uk/ about 15-20mins from campsite
In minehead you have butlins , there's the waverley paddle steamer which is the last sea going paddle steamer or theres the motor cruiser balmoral which do trips along the exmoor coast or over to lundy island or over the bristol channel to wales.
Go for a drive up onto exmoor and you could go looking for the exmoor ponies before heading back down somwhere for a cream tea.
There's the birds of prey experience places:

Your campsite is right under the quantock hills so if you want a walk or bike ride thats a good place to head to , if your willing to travel maybe 40-50mins you could get to yeovil and visit the fleet air arm museum and also the haynes motor museum.
