I'm refreshing this on a Monday morning; will probably do so periodically either until I leave on the trip, or have gotten more information then I can use.

My brother sends more info on his actual location; I've only known that he and Barb live somewhere between Lakenheath, where she works at the on-base American high school, and another smaller RAF/NATO base where Paul teaches middle school (junior high). This is their second hitch at Lekenheat; last time around they lived at Bury St. Edmonds, but this time, Paul tells me:

"We actually live just north of the border of Suffolk, in Norfolk."

An additional factor: looks like my wife and I will be accompanied by our youngest son, who won't turn 21 until February. Will his underagedness prevent or complicate our visiting pubs? He can usually avoid questioning about his age in relaxed, low-security settings, since he's about 6'1" tall. On the other hand, he's skinny and baby-faced, with extra-wispy facial hair, so on close inspection he doesn't really look any older than he is.

Thanks to all who have contributed advice; I've sent personal-message thank-yous to the three members who responded, but couldn't do that for "guest." So: Dave, thanks to you as well.
