The year I got married 8 other friends got married we would have run out of time for our own honeymoons if we had all done this.
Quite a lot of my friends didn't have Hen dos as we where to the four winds by then, I had 3 to make up
I realised that I could do one in my home town with my female family and best friend, just drinks out, 1 in the town I lived in which I shared with a work mate who was getting married the week before me, comedy club and night club and then one the night before the wedding for everyone who had traveled up by then this was to another town. I did the leg work as I wanted fun with people, DH Didn't have one except by default the night before the wedding to.
Only time I have heard of a hen weekend where I thought excellent, was my cousins bride to be and her matron of honour (her sister) got treated by their Mum to a spa weekend as a suprise, she paid for it all, organised with both her future SILs that they would be off work to look after their children, (mid week break as both on SAHM) at a hotel 3 miles from home as she realised they would both not have relaxed if they had been miles from home, she paid for 4 spa treatments all the food and drink and in a moment of brilliance managed to arrange for her daughters hair dresser and make up person to come and do a practice which my cousin and his wife to be couldn't afford to do, just before she took them both for an up slap meal.
Their wedding was similarly lovely, village hall and buffet, dress borrowed from a friend, flowers by Mum in law, booze by Mum handily a publican so she arranged the licence and charged cost price, fantastic
I feel for your friend I do think if I am honest I can't think of anything better than the excuse to be with my nearest and dearest female friends and family, but the reality is it is expensive, uses precious holiday, and if we have other responsibilities we have to juggle them.
My best friends been married twice never had a hen do, never made either marriage less special.
