There are so many amazing places on our doorstep in Europe.
i live in Ireland so flights are more expensive than the U.K., but for example this month, flights to Lapland return under 100 euros op, self catering accommodation quite cheap (post Christmas). This would be a once in a lifetime trip while kids are young.
there are cheap flights to Spain. France, Germany etc you can get some good deals.
Id make a list of places you like, your budget, and type into chat gpt to get suggestions you’d be surprised at the great options you will get especially if you ask them to come up with additional ideas
I highly recommend trains in Europe. I like Germany, my brother lives in Berlin, the public swimming pools in the summer are amazing and have very cheap entry, amazing parks and zoos etc. He’s just back from a spa hotel just an hour outside Berlin - 65 euros per person per night (with breakfast) - heated outdoor pool etc. A night or two in that would be lovely (leave the kids behind 😀)
there are lots of great forums where people talk about how to save money eg bringing food and car v flying etc. and costing routes.
eg some people use ‘Sun vouchers from paper, when park sale are on, how the weather is in certain campsites during ‘shoulder seasons ‘
perhaps if you have a bucket list of places to plan towards you can keep an eye on flights, again forums etc are great for advising sales and when to book flights
This week is the one that everyone gets a little down post Christmas and starts thinking about holidays so you are not alone !
