My number one tip. Do NOT go in Feb half term. It is really really expensive and really crowded. Also, if you are meaning Feb 2026, flights are astronomical by now and a lot of accommodation will be booked.
Go in the first week of Easter holidays instead. It is much cheaper and much quieter as France and other skiing countries are (mostly) not on school holidays then. Go somewhere reasonably high and snow sure, or somewhere lower but that has quick lift access to higher slopes (this may work out cheaper than a high resort).
Speak to an agent like Ski Solutions who can advise on suitable resorts. On the plus side, as beginners you don’t need a big ski area so smaller cheaper resorts will suit you, but if going at Easter make sure their nursery slopes are high enough.
Number two tip. Check your budget. Flights and accommodation are just the start unfortunately. You will need lessons. It would be unsafe not to. You may well just want lessons for the morning rather than all day and go do something else in the afternoons. You’ll need to hire skis and boots. And you’ll need lift passes - though many resorts offer free access to the nursery slopes which is all you’ll need for the first few days, so you might get away with just a couple of days’ pass towards the end of the week.
Kit can be bought second hand on ebay /Vinted or not too expensively at Decathlon/Mountain Warehouse.
I wouldn’t bother with UK ski lessons. It’s expensive, the slopes are short so you spend most of the time in a queue, and you will still need lessons on holiday anyway. Save the money for the resort.
Self catering is cheaper but agree cooking is too tiring. Although more feasible if you haven’t skied in the afternoons. One option is to stop off en route to resort at one of the big supermarkets and buy a whole load of ready meals/pre made soups/stuffed pastas/quiche etc. Another option is to look for a chalet or chalet hotel - sometimes there are deals available if they just have a few spots left to fill in a chalet or chalet hotel, though this does mean risking waiting till fairly last minute.
