Madrid to Girona waiting for advance purchase for the first morning train then TEISA 300 bus to Garrotxa Volcanic Nature Reserve where we’re staying. Why are the Spanish tickets so random??
For a cheaper journey you might actually try buying separately Madrid to Barcelona and then, not necessarily in advance, Barcelona-Girona (at least check you date)
Nat Park to Valencia. It seems the TEISA 300 bus to Girona with a 2hr transfer for Girona to Valencia via Barcelona works best. Waiting for cheap tickets to come online. Should I buy as a through journey in case there’s a holdup on the first leg?
Again, it makes sense to check both options (meaning through ticket and Barcelona-Valencia separately). Doubt there will be any hold up on Girona-Barcelona leg, it's a major route with trains running very often
Valencia to Girona. Ditto
If you know the exact date, you can also try checking Barc.-Valencia-Barcelona return. Two one-way promo tariff ticket will be cheaper, but Renfe also offers return discount.
Girona to Collioure. Rodalies gencat R11 to Cerbere (buy at station); then I have found the train1euro (online) tickets connecting Cerbere to Collioure. I think I can buy a standard ticket at Cerbere if I can’t buy the 1euro online.
With the short journeys like this even full fare (3,7 euro in this case) aren't
I can have either a 1hr 10min or 11mins transfer at Cerbere. What’s the likelihood of a missed connection on these trains?
The departing train should wait for the passengers from the arriving one, so 11 mins should be enough, but if you have time you can always stop in Cerbere for a bit longer
Collioure to Perpignan. I’ll avail myself of the cheap 1euro fares if possible or the 1euro bus. Otherwise cash on the day.
Yep, nothing to add here
Perpignan to Montpellier. Again the subsidised fare or do you think it more prudent to book standard fares. I’ll have just landed in HK when the 1euros come on sale for that leg!! Or is there another way?
Why to pay more, if you can travel cheaper? Especially since Perpignan to Montpellier is already decent distance and paying almost 30 euro doesn't look like a good choice when you have a chance purchase your tickets in advance
I’m also thinking of using the Historical subsidised fares in this region. From my understanding I can buy these at the local train stations particular to the route i.e. Nimes or Perpignan, 2 of the 5 Historical routes.
The full info is here in French -

Montpellier to Niort (closest station) or La Rochelle Ville or Poitiers. There only seems to be one train per day via Bordeaux, the others go through Paris but there is a selection. These also seem to be online now so I’m running out of cheap fares.
Well, France is often very Pariscentric, meaning that it's faster to travel via Paris, even if geographically Paris is a detour. If you want to look at some option not involving Paris, then would suggest to check the DB website for timetable (it will show you possible options, while then it will be a task to figure out how to buy it from SNCF)
Niort, La Rochelle or Poitiers to London. I looked at flying but by the time we’ve driven to the airport, hung around and taken the train/tube into London it seems to be just as easy to take the train to Paris & St P. Trains are more frequent (Sat or Sun) and we could allow a few hours layover in Paris - once we’ve stored the bags. Your thoughts please if there are any cheap alternative train tips. If we’re re travelling both ways Paris to Niort (for example) is it cheaper to get a return ticket?
In France return or one-way it usually doesn't matter, more important is to catch promo tickets, however witht Eurostar trains sometimes it might be cheaper to purchase not from Paris, but from some earlier relatively big French station (in your case e.g. Poitiers) + make sure you check both Eurostar website and SNCF website, those might have a different price for the same departure
London to Norwich rtn
and possibly London to Chester rtn or I could combine the two journeys i.e. London - Norwich - Chester - London
On the Nationall Rail website (as aggregator of all the UK rail operators) you can purchase so called "Advance" tickets for very decent money compared to the standard fare (10 vs. 20+), same story is for London-Chester (20 vs 80+)
