Power in Tent

We have just purchased a tent and will be doing a lot of family camping this year in holiday/caravan parks.

I'm just a tad confused about how to get power in the tent. I've tried searching these forums but haven't found a direct answer.

Our tent has an opening where you can bring in cables so that's not a problem. But can you plug a power board directly into the holiday park 240V power outlet? I don't think you can...

So what's the best way to power multiple items in a tent? (ie. computer, light, fridge etc)

Thanks

PS. I'm sure this is a very basic question but obviously want to make sure I'm following holiday park guidelines and safety/compliance regulations.
