My itinerary last time was:
Day 1- Edinburgh (calton hill- very jet lagged-right after a 15 hour flight)
Day 2- Edinburgh (drove to Stirling and Falkirk for Day Visit- saw Castle, cemetery, Kelpies, Wallace Monument)
Day 3- Edinburgh (royal mile- Castle, National Museum, etc)
- in Edinburgh we stayed outside the main city in Ingliston right near the airport at a place called Norton House Hotel and Spa- this was one of the nicest places we stayed. Beautiful grounds, friendly staff, and lovely rooms. It is a bit pricey...but I liked it a lot. Also right near the airport-- but not loud at all.
Day 4- Alnwick - to see Alnwick Castle--(this was great and a must- I HIGHLY recommend it- very well kept grounds, lovely garden and place to visit).
Stayed at a place called Birchwood House in Morpeth (about 20 minutes from Alnwick) - quite nice- easy to find- large breakfast spread, friendly host.
Day 5-Visited Hadrian's Wall on way to North Lake District- Saw Castlerigg (sp may be off) stone circle, drove through Kirkstone pass to Ambleside- Lake District in Evening-- very very LONG day.
Day 6- Lake District - Ambleside/Beatrix Potter's home, Windemere, and a boat trip where we ran up on some rocks due to my friend being distracted by a swan--ok she can't really drive a boat well and didn't listen to the whole - keep 30 meters from shore thing---but we did see a swan when we were stranded and it was super amusing...an emergency fellow came and fetched us- and blamed the swan...
Stayed in the "Lake House" hotel. Was clean, they also hauled our rather heavy bags upstairs for us. 2nd Bed was...uneven.....but I was so tired I really could care less.
Day 7 Drove to Wales- Llandudno- used as base (3 hour drive). visited Bodnant gardens in AM, then Conwy in afternoon.
Day 8 - Visited Caernafaron, a manor home (Rha?? something--a slate mine owner's crazy palace built off of slate money) Beaumaris Castle, Llandudno. Lots of castles...
Stayed with some chatty Welsh couple in a bed and breakfast. Probably should have gotten a hotel...place had no AC and loud seagulls.
Day 9- Drove around about Snowdonia, Fairy Glen, Capel Gormon, abandoned monk chapel, some other welsh castle with a Dwollydyn? - stayed near LLanwrst on a farm. (I'm bad with Welsh spelling...).. saw a very large ill cow on a field.
The farm was interesting...http://www.siabodhuts.co.uk/
-didn't do the huts but opted for the indoors. Really quiet and very clean place. They give you a sitting room, a bathroom, and a large bedroom. They have a very happy sheep and we were able to pet it.
Day 10- North- Cotswolds- cierncester-3 hour drive.- went to a farm park and an estate owned by Henry VIII's former wife, then another small manor home.
Place we stayed at had terrible parking-- (i.e. scary nightmare parking)- had to park up on the grass and try to not hit anything. Room was literally uneven.
Day 11- South- Cotswolds-chippenham- took a break from touring to look for more luggage
Stayed at a pub/hotel place....yawn..forgettable.
Day 12- Bath- drove from chippenham to stonehenge in the AM, then back to Bath, visited abbey, baths, etc, then went to hotel to check in, then returned via taxi (to avoid the traffic and fees) to go to the spa for 3 hours.
Stayed at Brindleys- highly recommended!
Day 13-17-London- took a train to London the next day after dropping off the rental car.
I felt the area in the Lakes was a bit rushed, Cotswolds to me were very boring, Wales was interesting and I think we spent just the right amount of time there-- though we were a bit exhausted by day three and just collapsed at about 5pm from all the walking up and down hills and castle stairs. We could have probably used one more day in Bath.
I'm headed back to do a middle route of the country in about three weeks and avoid switching hotels as much...but I'm also staying a bit longer.
