I'm not keen on lots of people where I travel either. We have three DC and the added complications of the eldest having severe Autism and DH is a teacher so travel times are restricted.
We enjoy lots of travel though. We're currently in Croatia. Large car hire was £14/ day, flight for the five of us under £200 and a big five bed house with pool etc 700euro. We spent the morning in a tiny fishing port paddling in the Adriatic in the sunshine. Ate ice creams then brought fresh sliced meats and cheeses, a bottle of wine and headed back to our villa on a small holding in the hills. We've all mod cons here (dishwasher/ washing machine etc) plus private swimming pool, five a side football pitch and badminton net. The children each have their own bedroom and the internet is good so screen time is helping with babysitting (and I dont feel guilty).
I enjoy nice foods but don't really enjoy gastronomic experiences with three DC (and autism in the mix) so my from pre DC sacrifice is eating out on holiday.
We tend to do shorter trips out most days. We went to Dubrovnik a few days ago (40 min easy drive), as it's off season parked right by the city walls had a good run around peeped through lots of windows out to sea, went up and down an amazing number of stone steps.
In Feb half term we went to Finish lapland (flights under £300 from a regional airport - my parents wanted a memorable family holiday so helped out with this one) accomodation was £2000 for a week (shared between three families) for a 7 bed appartment, again all mod cons. We took grandparents, sister and her family and shared childcare/ activity opportunities. BIL had a couple of days on the slopes, lots of half day kids clubs activities were available and there were many DC I'm not convinced could walk in ski boots almost to the top of their legs with tubby little skis - they could barely fall over if they tried. No pushchairs, just sledges transporting children around the streets.
Another amazing place we took the children was Chamonix at October half term. Technically the end of summer season so the lifts to Agile de Midi still open but some skiing available too. Little playpark and child friendly activity like swimming in the town but lots of adventure to be had too.
We travel a lot. Last Easter we did Florence, Rome and Venice. Flights to Venice then first class train around (children were free when travelling with adults 1st so it worked cheaper than 2nd) in Rome we did a hop on/ hop off bus type thing as we only had one full day but it was easy with the children. In Venice we got a boat pass so when the children needed to sit down we hopped on a boat and took in the canal views. The casual dining experience in Italy worked very well for us ordering a selection of mains and sharing them out.
When DD was 3 we went to Iceland that was amazing with DC - as with many parts of Europe children were free at activities but also in many restaurants - so it really wasnt wasted money. We went out whale watching full warm suits and lifejackets supplied, watched geysers, saw magnificent waterfalls, got caught in the middle of a horse drive with hundreds of ponys being moved down the valley around us. We went to the black beaches, boiled eggs in a stream, swam in many thermal pools (young children free, moderate charge the older they get but other than the tourist pools, the local pools are relatively cheap. We've been back twice in summer and once at Christmas - swimming outside whilst it snowed on us, mind blowing. DC jumping out the pool onto the snow and crunching through it to come down the water slide back into the warm thermal waters. We did have to share several olympic size pools, numerous hot tubs, steam rooms and saunas with about 4 other people though so our £12 family entrance didn't give us exclusive use!
Denmark was incredible with children too, we've also done a couple of cruises which can be great for the balance of family time and opportunities for the children to do fun children's activities as well as allowing a bit of adult time. Didn't work well really in value terms for us with DS1's Autism though. Too much stimulation in many areas of the boat.
