I had to come to terms with my infertility about 17 years ago. We spent a year embracing being childfree as opposed to feeling childless and did lots of amazing travel - not just during that year but each time an IVF cycle failed we booked a holiday to get over it.
Eventually we realised that all the luxury travel in the world would not take away our sadness so we adopted. I know it's not the answer for everyone.
Unexpected delight came from - the long term group of close friends we made at our adoption preparation workshop. They are more like family now and our shared experience has bonded us for life.
Also
Camping - it was my idea of hell before I actually tried it and am now a massive camping bore.
Cruises - also my worse nightmare until my in laws took us on an all expenses paid family cruise for their anniversary. Got off the ship and immediately booked another cruise for the following year.
Beach huts - had never thought much about them but a good friend owns one and we've been lucky enough to spend a lot of time there and each time I just feel so relaxed and happy. Hired one for a week a few summers ago and loved every second we were there. Am now on the waiting list to buy one.
Ascot - my heart sank when a friend announced her birthday celebration was to be there. I dutifully bought my dress and hat and prepared to endure it. I was so wrong. Friend had booked a table for the whole day in one of the restaurants and it was a fabulous and enjoyable day. Can't wait for an excuse to do it again.
Lots of other experiences have delighted me but I knew they would before we did them so they don't count!
