I'm not a spa lover , a high flying CEO nor am I mean
Out of interest @ForestFae have you actually asked your children what holiday they would like. ? If it's that genuinely they are 'mini you' then here's a few suggestions of holidays I've been on that I think they would like, given the nature/castles/folklore thing
1 Black Forest down as far as Lake Constance- lots of camping, cycling, hiking , lakes and castles - probably avoid July and August as it's consistently sunny and warm but does thunder quite a bit
2 Brittany-concarneau - standing stones, great camp sites, forests, pretty town cycling, hiking
- Denmark - Copenhagen and coast- having just lived there for 19 months, excellent city, cycling coming out your ears, kayaking, white sandy beaches, castles galore , the fantastic bridge to Sweden , superb camping and 'summer cottages' and sunny a lot of the time in summer but not hot - not humid, really fresh air
4 Sweden- similar to Copenhagen but a bit cheaper, forests, lakes, superb food, high standards, sunny but rarely hot
5 Canada - castles, hiking, camping, superb food , forests and hiking and not too hot
6 krakow and Zakopane- Poland. Lovely city plus mountain resort, swirling rivers, fantastic nature , cheap , great food and if your kids are old enough/up to it
I've enjoyed all these too- they just happen not to be UK -
For anyone who isn't into the flop and fly and has active kids but likes going out of the UK , they are all well worth your time -- I can't guarantee wall to wall 32 degrees
And sun but in all honesty I've had great weather in all of them for most of the holiday
