I took my 2 dc to Thorpe Park, with two of their friends. My two have no fear and will go on every ride that they are tall enough for - the eldest this means everything, the youngest this means everything bar the very big roller coasters.
They chose friends from school to take - I spoke to both sets of parents before going, explained that we would be going on the rides. That the older 2 would go off and meet us at regular points so that they could go on the large rides, and that we (dh and I) would stay with the younger two.
We paid for it all our treat.
But when we got there neither child would go on the big rides for their heights, so my eldest was unable to go on the really big rides as they had to queue up for the medium rides, my youngest went on the medium rides with the older two, but the younger friend, would hardly go on any rides.
When we got back and deposited the children home, the parents asked whether it had been a nice day etc. I explained that the younger one had hardly been on any rides, and that the older one hadn't been on any of the big rides.
Both set of parents then said words to the effect of 'that's why we don't take them, because they don't like the rides!'
AIBU to think you could have told us that when they were invited and we could have gone out elsewhere with these children not to a theme park, and invited children who do enjoy theme parks with us?
