Cindy-
We love the Detroit airport! I think we fly out if there far more often than CLE in the last 10 years. Flying out of Cleveland gives us few nonstop options going anywhere! We both have Global Entry cards and love the convenience of arriving back into the US with them. I also have Nexus for Canada as my daughter and I go to NOTL every summer (this June will be our 23rd year!) and we love being able to use the Whirlpool Bridge with no lines.
We flew Virgin Atlantic from DTW to LHR last summer - big mistake! At that time, they were not set up for TSA precheck, although they may now be - plus the plane was so old and even the premium seats were so uncomfortable. We flew home on a Delta flight which was much better. The drive to Capelulo, Wales was a longer drive than we normally ever do, but we were meeting my cousins in northern Wales and had to start out there. My family is Welsh and I still have cousins with whom I am very close living outside Swansea, so we visit as often as we can.
I do not believe there is a train from LHR to Oxford - just a bus which I have heard is quite good. The train departs from central London to Oxford. Our soon to be son-in-law is from Oxford and we have visited his family in Oxford several times in the past few years although we always rent from Sixt and drive. I have never been to Bath, but want to visit that area one day.
Italy is the country I love the most. I attended college in Florence for one year many, many years ago and our daughter attended college in Rome for a semester. Italian was my minor in college. We try to visit different parts of Italy every 2-3 years, if possible, as my husband now loves it as much as I do - his father's family is from Sant'Agata di MilItello, Sicily and he still has relatives there. This Fall, we have rented a villa in San Gusme (about 20 minutes east of Siena) for a week and will then spend our last 5 days in Rome. My very favorite area of Italy is the Val d'Orcia - I could spend the month of October there every year if I could convince my husband!
So many places to see!!
