I think people (like us) who already have cut back, and already have 14 year old car, buy cheap food, cook from scratch, don't buy clothes/shoes (I have one pair of trainers, and clothes 20 years old), no sky sports or sky anything, very cheap internet, we all have old second hand phones off eBay, no contracts, top up pay as you go about twice a year, no haircuts (we do them all ourselves), rarely drink, don't smoke, no gym membership, always make lunches, no takeaways, no going to the pub, no going out at all... the list goes on.
We already do all of that. But there are no funds for holidays.
I think when (some of us) read about those saving for holidays in those ways, it reads to us, that we maybe didn't realise those things and it's our fault we can't afford a holiday because we choose to prioritise different things.
But we have been very lucky in the past when we earned more money, and we were able to go away, and make some amazing memories. We even had a free holiday last year (long story) so we felt incredibly lucky.
We are starting to sell bits on eBay, and have £165 so far in the holiday fund, but that's not going to get us very far 
Anyone we know who is going on holiday abroad, either benefitted from buying a house a long time ago, or benefitted from the very low interest rates.
We're going to put the £165 towards our garden and have a staycation
