OK, I've read previous postings, Rick's books, the websites, etc., and I just can't quite figure out what I should do. Here's our plan. We're in London for 6 days, inclusive of our in/out flights at Gatwick. Most of our time will be in zones 1 and 2 though we want to take a trip out to the family burial grounds near Epping (zone 6). Our other day trip will be to Windsor. We walk a lot so I don't know that we'll use the Tube "excessively". Do I get a 7 day Oyster? How do I address the trip out to zone 6? I guess if I make a mistake, it's only money...
Thanks in advance!
