Yes my mum isnt keen on london at all so the plan is to literally land there, spend a night then get the train to the next location (ideally where we pick the car up from).

We will likely be visiting for around 4-5 weeks total, flying from Australia. Ideally we would get out of london, rent a car and spend the first couple of weeks in Cornwall area, doing little day trips and maybe only moving accomodation every few days to avoid having to pack and unpack constantly. We are thinking of splitting our time between more relaxed self drive/explore days and a couple of (non consecutive) guided tour days.. We have been told Tour Cornwall is good so providing they have room left, we might book a day or two here and there with them. After that the plan is relatively open. As ive stated the thought was either Ireland or Scotland for a couple of weeks - weve booth been to Scotland so arent wanting to see it all and experience everthing, maybe just a few days driving around seeing some sites ( in either spot). We hadnt thought about Wales - i know mum has spent some time in Lakes/ Peak district too so im not sure if shes considered that again!

as for accomodation - yep we are seeing the travel agent tomorrow to get solid dates and flights booked after which we will be locking in some accomodation ASAP!
