A month or several ago, while we were wandering around talking about something or other, A somewhat sheepishly said that he thought Animal Experiences were a Really Good Present Idea but he was concerned it was Cheating in some fashion to get me animal experiences for my birthdays because I'd Thought Of It First.
While I am absolutely a fan of saying "look at this ridiculous(ly expensive) fountain pen! wanna buy it for me?" and indeed "hey, want to buy us afternoon tea at Ruby Violet?" I am also very much on board with Surprise Animals, and that is why this time last week we were settling down to sleep in a tiny two-person cabin overlooking the Chilterns having thoroughly worn ourselves out with Keeper for a Day at ZSL Whipsnade Zoo.

[ID: one wall of a light-coloured wooden cabin, with a print on canvas of a photograph of two lions. to the lower left, pillows in white pillowcases are visible. to the right is a chest of drawers, on top of which there are a cube-shaped box of tissues and a clear glass vase containing red and yellow roses, and purple and red-and-yellow tulips.]
This had entailed getting up early enough to Be At Whipsnade for 0830, which was made all the more painful by making a surprise late-night wheelchair delivery the previous evening, but nevertheless we had an excellent time of it.

... and then it was time to fetch the car from the main car park and head up to the lodges for the Zoo Sleepover.
( Lookout Lodge, in bullet points, to be expanded upon at a time that is not bedtime. )
