I know this is a no brainer for most of you, but I'd appreciate your opinions.

October ROC -EWR - LHR had a major schedule change. We are a retired couple in no hurry, more interested in comfort than moving too fast (OK, a minor health issue that makes me walk slow). We usually like long connections for international destinations. Options are ROC-EWR-LHR with 6 hour layover of ROC-ORD-LHR with 2 hour, 18 minute connection? We will have access to the Polaris lounge either way. Obvious concern (?) is late afternoon/early evening flight into ORD having late arrival.

Wife prefers later arrival into LHR, 10:30 to noon time frame

Am I just being silly?
