I wouldn’t waste your time locking the tent. First off I have never had anything stolen from my tent and none of my friends or family ever had anything stolen when camping.
The lock will just catch a persons attention, if you lock it they know there is something in there of value and will just cut through the tent to get to it, it wont deter them at all. A ripped tent isn’t worth putting a lock on the tent to save your clothes, unless there is a homeless man looking for clothes I don’t think you will be bothered. Just keep your tent zipped shut. If you are that worried about it have someone in the campsite at all times.

As for the young kids keep it interesting and fun for them but don’t push them too hard or long if you decide to go for a hike. Let them play in the ponds, catch frogs/turtles/ salamanders, let them run through puddles, play in the rain; all stuff they normally cant do when they are home.Let them be kids. Get them interested in fishing if there is a lake or river near by. Go on a nature hike and try to spot animals. Have them build the campfire, stacking wood and such so you can light it, let them feel they had a part in creating that. Teach them how to start a fire. Let them pee behind trees. Just let them be kids and they`ll have a blast.

You need to have electrical sockets protected from damp and damage whether at camp or in your back yard or garden. It’s just the same.
Yellow cables are easier to see and are therefore safer to use on camp sites. You can use black ones, blue ones, all sorts. Some very heavy duty cables are in bright blue.
The end that plugs into the campsite socket is just a standard fitting three pin plug but one designed for outdoor use.
You can buy them in B&Q and other DIY stores and wire one onto a long cable or buy a lead already made up.
The link didn’t work for me, but here is one which might be the same one…I just did an eBay search for a similar item.
Http://cgi.ebay.com/Trailer-tent-camping-electric-hook-up-cable-lead-Yellow-/270608690187?cmd=ViewItem&pt=UK_Cables_Hookups&hash=item3f0188ec0b . . . . .
It’ll be fine for camp if ten metres, around 32 feet, is long enough for you.
The price is OK but the postage makes it expensive. You can get one in DIY or electrical shops for less than £20.
Just ask for a lead with a waterproof plug and socket on it.
You can take an extension lead from home if you have one and use a wooden or plastic box or a plastic bag to keep the sockets covered and dry if they are going to be outside.
Some people tie a plastic bag round the campsite hook-up socket, which is normally on a short post sticking out of the ground. Or put a plastic bucket over it to keep the rain off. Doesn’t need it because the thing is made for outdoors anyway.
Sandwich boxes are handy for keeping sockets dry. Just put a couple of wide slots in for the cables to go through and the the socket fits nicely inside. If you use a four or six way socket from home just get a long food container to put it in and put slots in for the cables so you can fit the lid on. It’s safer in case you get a bit of leakage in the tent but in dry weather you’ll be OK without the box. Just be careful where you put the sockets so they are safe and the cables can go in a safe route to them.
Keep cables neat round the tent so you don’t trip on them and use mats over the cables if you have some in places like doorways to keep them safer.
10 amp hookup just means you can use up to 10 amps total on one cable so you need a cable and sockets rated at 10 amps or more.
In the tent or trailer you can use items that together don’t come to more than 10 amps.
In UK that gives you 2300 watts of power available.Multiply amps by volts to get watts
It used to be 240v in UK but now it’s officially 230v, not that it makes any difference to most stuff anyway.
That gives you say a 1000 watt electric fire, two 500 watt cooking appliances like grills, and 200 watt TV and 100 watts of light.
Any combination that adds up to no more than 2300 watts is OK.
In USA on 120V ten amps gives you a total power available of 1200 watts.
Have a good time. It’s OK on camp sites…nice life.

Just seen where you are from another Q. Looking to see if a UK answer was really needed although it said UK on the eBAy link, just making sure.
I’m from near Dunstable,haha. I was at Willen Lake a few days ago.
In MK you’ve got B&Q, Comet, Waites, Homebase, Aldi. Plenty of places to get a waterproof extension lead.
You can get a 10-amp or a 13-amp lead. Doesn’t matter at all, so long as you don’t use more than 10 amps when it’s plugged into the camp site socket.
If you buy one with a waterproof plug and just one waterproof socket the other end it’s more useful and you can take a 4-way or 6-way adapter from home to plug into it. That’s what we do. The same lead does for my mower at home too and other outdoor jobs.
Have a great time.
