Since we arrive at Heathrow in July at 10:45 a.m., we are considering catching a train on to either Bath or Oxford since we probably cannot get into a London hotel until midafternoon or later. We will have a Britrail pass, and will be returning to London some days later.
Has anyone taken either of these train routes? Do we have to go into London first--if so, should we use our Britrail pass?
Thanks!
