- Is the most reliably relatively cheap way of going between Hemel Hempstead / London and Mannheim by train using an Interrail pass and going via Brussels and Frankfurt, avoiding ex-Thalys services?
- Living in Mannheim for at least ten months, is it fair to say that the My BahnCard 50 would be worth the cost? Two return intercity journeys per month at €10 for saver fares each way saves €10 per month, and as far as I can tell there's no minimum spend or time limits for the discount to apply.
- Apart from the D-Ticket (or Semesterticket), are there any other discount cards worth getting? The Carte Fluo for TER in Grand-Est's €1 for under-26s so that's worth it even for one journey. I'm interested in discount cards for museums etc. as well, not just transport. The only one I've been able to find is the Museums Pass Musées, which at CHF 149 is more expensive than I'm willing to pay.
- I'm looking for recommendations for day trips from Mannheim. So far near-ish (doable in a day without intercity services) I've got Heidelberg, Mainz, Frankfurt, Luxembourg (City), Heidelberg and Strasbourg as places I've been to before and want to go back to, and Mulhouse, Stuttgart, Tübingen, Karlsruhe, Koblenz and Trier. I'm looking for further away places as well, provided it's possible to spend most of the day there / enough time to see enough of the destination.
