2 years ago I did a 9 day tour of Scotland with Presitage Tours. It has nothing to do with Disney. The tour I did was called Royal Scotland and we visited all the castles & "royal" things in Scotland. It's a bus tour and the bus only holds 14 people max. We had 11 on our trip. We did over 1500 miles in 7 days (2 were travel days). It was the best tour I have ever been on. Our tour guide lived in Scotland so he knew the area well. We did the highlands and lowlands and learned a lot. We went in July and it did rain in the highlands. Loved the trip. I believe we paid about $1100 per person and it included all meals, hotels, tours, etc. Only thing I spent money on was stuff I brought back. Great trip, I would do it again.
PS: I did this with a girlfriend and we did not feel out of place. The rest of the traveling group were couples and 1 single Professor from Cambridge. She was a lot of fun and didn't feel out of place either.
