Actually going against the grain here I'd say staying in a house will be a hell of a lot easier with 2 small children than all cooped up in a hotel room
If baby or toddler wake one of you can take them to the kitchen / living.room minimising disruption to everyone else
You have room to spread out once dc ate asleep. You have a fridge & washing machine which were essential when travelling with tiny children in my experience.
We've always travelled a huge amount with our dc & until they were 8 it was all long haul - Australia multiple times, Canada, Asia etc.
When v small we always had apartments so we'd have breakfast in the morning at home & could keep juice, cereal, milk, fruit etc in the fridge. Plus wine, beer & water - essentials!,
We tended to go exploring after breakfast & we'd have a nice lunch out - usually sharing from our plates with dc along with crackers etc. Often we'd make that our main meal meaning we would have wine / beer & nibbles in the evening when dc were asleep.
Overtimes we'd have more of a picnic lunch & we'd get some lovely takeaway again once dc were asleep.
We kept cooking for dc to a minimum but made easy quick things they liked - scrambled eggs, pizza, pasta etc.
Even if you've no Internet there could well be a TV with some kids shows on it. Our dd watched a lot of French Canadian TV one year without having a clue what was actually going on in the cartoons but it didn't seem to bother her a bit. We watched lots of early morning episodes of Caillout.
I know it feels overwhelming but you may look back at this as a wonderful memory of you all being together, especially if there may not be many more opportunities. If you can relax & go with the flow & view it as an adventure you could have a brilliant time, but I know that's easier said than done
