The breakfast at the Royal Sportsman was actually reasonable. The whole hotel experience scores a 6.5 out of 10 - except the Tesla charger, this hotel does not really offer anything special for the price.
Today we had lots of scenic drives planned. By the way, the rainbow in the itinerary table means 'scenic route' - apparently, most people think of other things when seeing a rainbow. I just couldn't find a more appropriate emoji - but I am open to suggestions in comments.
First, the remainder of Snowdonia. Although beautiful, it was a little too crowded for our taste. Also, driving for a long time along a road surrounded by trees - with no horizon - tends to be tiring for the driver and induce nausea in the passenger (at least that was our situation after an hour or two).
After Snowdonia we continued along mountain roads passing Tregaron (B), the beginning of the Abergwesyn pass (C) and Llandovery (D on the map, nice little village). From there a long climb to the Brecon Beacons National Park mountains, but that drive is 200% worth it: the views you get on the top are unforgettable. Lot of 1-track-driving again, but by this time we were used to it.
The Bridgend Supercharger - actually called SuC Sarn - has 8 stalls and all of them were free when we arrived - despite Tesla's information showing 2 stalls in use. We had our dinner there at Starbucks - we were pleasantly surprised by the freshness of their salads and hot meals. Recommended if fast food is all you have time for.
The last stretch to the hotel was just 25 minutes. This was the second hotel on our itinerary - Copthorne in Cardiff West (Cardiff is spelt Caerdydd in Welsh). We found this hotel via Hotwire (thanks to Jasper for recommendation!) - this site offers 4-star hotels for competitive prices, check it out. Unfortunately, the pool closed at 20:00 because of the Bank Holiday today, otherwise there is a gym and the rooms are big.
A conclusion: too many 1-track and winding routes makes a day trip long and tiring. For the future, we should not plan as many 'scenic' kilometres without a good rest.
