OP there has to be a happy medium!
Before I had children my husband and I used to have three holidays a year, one to the Caribbean, one medium haul and one short haul in Europe.
We have a similar income to you, live in a very affluent area and have about 70% equity in our home.
We work in the public sector where wages have stagnated for the last decade and the cost of living increases and as we remortgaged in November we are feeling the pinch of higher interest payments on our mortgage, and our disposable income has been hit!
To balance the books we have a UK break for a week each year, and a mid haul holiday! We have lots of days out because we cash on club card vouchers for National Trust membership and theme park tickets!
Our UK holidays have been Wells (took the kids to Stonehenge, see the Magna Carter in Salisbury, Wookie hole, Glastonbury and Chedder gauge and obviously went around Wells) but have booked houses in Scotland and York with hot tubs too! We went to Futerventura in the summer and did a tour of Lanzarote by ferry - staying at a five star hotel AI hotel. Both holidays cost less than half the price of one trip to the Caribbean and allowed us to save towards a garden room we plan to build later this year!
This year we are going to Tunisia and staying in a hotel with free access to to a water and theme park for two weeks AI for two weeks again at less than half of the price of going to the Caribbean! Plus trips, eating out etc… is very reasonable.
Yes children are only young once, but there are plenty of fabulous places to visit that are far less expensive than heading across the Atlantic- why not halve the cost of your holidays for a couple of years and pay down your debt over two years?
It doesn’t have to be all or nothing- there is always a compromise to be made that can allow you to enjoy life without breaking the bank!
Set a sensible plan to reduce frivolous spending, and pay down debt whilst still enjoying life!
