Geoffery,
We're (2 of us) heading to Bandon week after next. 3 days on site, 4 nights, 2 days travel R/T PDX. We're going off high season so the cost will be less.
The same 2 went to Scotland last year. We come from different places and met in Cruden Bay. Iteniary:
Day 0. Arrive EDI/ABZ
Day 1. 36 - Cruden Bay
Day 2. 36 - Castle Stuart
Day 3. 18 - Murcar (This was an open tournament. Check the websites to see if they're available when you're going to be there)
Day 4. 36 - Royal Aberdeen Balgownie
Day 5. No Ballot. Drive to St. Andrews. 18 Lundin Links
Day 6. No Ballot. Up at 2am, in Queue at 2:30am. 18 TOC, 18 Levan Links after pm nap
Day 7. 18 Carnoustie
Day 8. 18 Kingsbarns
Day 9. 18 No Ballot. New Course, Drive to EDI - Depart
You can play different courses obviously, but including B&B, rental car, and caddies, it was about $3400 on the ground. You'll do better with the current exchange rate. We made all the arrangements ourselves, and called some places up that week, or that day to finalize. We had some flexibility so we didn't play all the time as there isn't much fun in making a tee time that day in a teeming rain.
For comparison purposes here's what I did with a different group in Ireland back in '09. Costs were less - about $2800. We had 7 go on this trip.
Day 1. Stuck due to T-Storms in Newark
Day 2. Fly to Belfast.
Day 3. am, Arrive Belfast, drive to Rosapenna, Donegal. 18 Old Tom Morris
Day 4. 18 OTM AM, Rain PM - Pub
Day 5. 18 Sandy Hills AM. Cruitt Island PM
Day 5. 18 Sandy Hills AM. 18 OTM PM
Day 6. Drive to Port Salon. 18. Drive to Portrush
Day 7. 18 Royal Portrush Dunluce
Day 8. Port Stewart Strand AM. Riverview PM.
Day 9. Giant's Causeway. 18 Royal County Down. Drive to Belfast.
Day 10. 18 Ardglass

Bandon is much easier to plan from a logistics standpoint - everything is right there. Write down what you want to accomplish. If you're going to Scotland or Ireland, do some digging and see if there are any open tournaments to enter. Those can be fun and will certainly improve on the cost per round figure.
I suspect you'll have a great time whichever direction you go.
