I think you need to decide what is most important. If you want a nice big bathroom with separate shower then you need the front double (or 2 singles) and side dinette giving 2 bunks, and rear bathroom. If you can do with a small bathroom then go with the beds either end layout.
Our end bathroom is a real bonus for the children (aged 3 and 5) and I really wouldn't want anything smaller. Our caravan is small with front double and side bunks, but will be fine until the children get too big for the bunks. For us, the bathroom just makes things so simple with the children.
I personally love our layout.We have three children age 7,3 and 2 and we have the double at the from and then a side wash room with a sectioned off sleeping area withe put way bunk a the back.It just gives us more space and privacy to sit and chat at night at the front of the van whilst not disturbing the children if we watch tv or need to go to the loo and then during the day the extra space at hte back of the caravan allows us to all eat together too.It can a be a bit of a sacrifice with that smaller bathroom but I tend to prefer that than the children perhaps not settling at night and sometimes you just have to weigh all the plusses and minuses when you see a lovely caravan that you like.
Good luck You really can't beat it when they start to toddle around in all that fresh air they love it.
It all depends on the age of the oldest child and if old enough for a top bunk.
We had a 5 berth, double at each end, but very small washroom so difficult to use shower. If oldest one came with us it was normally for a main holiday and he wanted to sleep in awning anyway.
So brought a 4 berth with side bunks and end washroom, loads of space to shower/wash and dress little ones and if they all come for a weekend we put the little one at the bottom of our bed, which i'm sure you could do with a toddler.
The better the onsite facilities the higher the fees and sometimes there are perfectly good sights, let down by the bad facilities, so an end bathroom can also save money.

never thought of it like that end bathroom type vans i mean and if it saves me cash happy days
Have you thought of top and tailing them on bottom bunk until 4 year old is big enough for top bunk. You could make some sort of bed gaurd to stop them falling out. Perhaps an old cot sid with a few well placed brackets or some sort of mesh with press studs that go under the bottom mattress and into the bed base and then press studs onto top bunk to hold in place.
we have 4 kids front double and side bunks,we also have end bedroom on awning for me and hubby ,my eldest is 11 and disabled so we have bedguards for him my five year old loves top bunk then other two get on double we get the awning,but i love the end bathroom for changing and showering kids good luck
