Club site morning leaving times

We very rarely stay on club sites due to cost and we like the space of cl's, but occasionally we stay on a club site in cheap season if it suits our location requirements. 

Im amazed to find out this weekend that there is no minimum early time you can leave. I assumed it was 8am or a bit later, but clearly not.

Yesterday a campervan left at 6am and this morning at 5:30. I come away to get a lie in as my usual work alarm goes off at 5am. Thanks to these 2 campervans, no lie in has been had. Looks like another week of driving my lorry without me being fully recharged. 

Is it too much to ask to sleep in until 8am? 

Rant over.
