when working as a nanny i would never spend that much... and would definitley not do so much in 1 day...
i had a great network of nanny friends which helped as we would (almost every day) either have friends and their charges to our house, or go and visit nanny friends at where they work.
I was lucky as most of my nanny friends (and me) worked in houses with either a Pool (and we'd all swim) tennis courts , OR HUGE garden with woods, OR super playrooms etc so once with friends it was easy to spend a day together without spending money.
Whoevers house we were at would cook a lunch for us all, (it all works itself out in the end), and there were enough dark bedrooms / travel cots for the younger ones to have their sleep as normal and we all had portable high chairs...
we would often have 3 nannies and 6 or more children sitting round the table to all eat the same freshly cooked lunch
Our visits would normally be the local parks (we might drive a few miles to find an extra good park) or country parks for and if the weather was good we would all take our picnics from home...
we lived close to the sea so could explore lots of different beaches easily as well
I always took my charges swimming EVERY week, to lessons in term time, and normally to a fun pool with slides / waves etc in the holiday (we all loved it) but i would always opt for the mother and toddler session (£3 for us all as opposed to over £10 at another session)
We would have a holiday planner and we would have 1 or 2 big trips out in a holiday (maybe 3 or 4 during the whole entire summer holiday)... eg the Zoo or a big farm park or steam train ride or something, all cleared with our bosses first.
I would NEVER buy the children anything from the shop afterwards, and therefor they didnt expect or ask for it, we would always take a picnic and the if we had an ice cream it would almost always be a mini milk or mr man lolly.
(This was only if picnic lunch was eaten sensible and behaviour had been good )
I always scoured the local papers / leaflets / internet for discount tickets for the attractions we went to, and if they did group discounts and we had enough nannies / children we would pay as group to reduce the cost further. Or i would join up with another nanny at the gate, and get a family ticket between us as often our youngest were young enought to be free
We were also members of the local farm and aquarium so would vist there "free of charge" most weeks as a free day out. We would also visit the library most weeks (but might do this as an activity with another nanny and their charges too, somehow things are more fun for everyone when nannies and children have friends
We had lots of bike rides, visited the free museums,
