FlyingFuck,
You're possibly confusing SpanishAbuelaSpanGran, our lovely OP/Watty's houseguest, with MNer Gramgram (who first suggested the coach trip, hence she being referenced in my prior posts and deserving of VIP treatment!) ? 
(Though of course SpanGran/ Watty / GTB and Ken would get premium billing too).
Though you've reminded me of a very good point: it'd be vital to have headset audio translation of guide commentary, in however many languages necessary for our International friends...judging by the amount of flags on here, that's a Hell of a lot!
Am ashamed, too, I'd neglected to make clear that our fantasy buses have also been converted to being wheelchair accessible, with frequent 'comfort breaks' at service stations for those weaker of bladder.
(TMI, perhaps, but important).
Shall I put you down as a vote for modern coach, then?! (Am keeping a tally).
