I also look at the aspects webcam every day! Aspects is a really good place to look for accommodation, OP.
if you think of London, and you think of the south bank, that’s how busy the two main shopping streets are during an August afternoon, by which point you’re on the beach.
but not so heaving in the morning or evening.
lots of people will tell you it’s ‘heaving’ but it certainly appears heaving if you arrive during the afternoon on a day trip!
parking spaces are indeed tight, and there are some pitfalls to avoid. Make sure your parking space is not in a garage (St Nicholas court for example, built in the 1970s with underground parking that’s extremely difficult for today’s cars and ditto piazza).
Also make sure the car parking is on site and not a mile away up a tough hill at the rugby club (it will still be advertised as allocated parking!).
There are some properties that have allocated parking at the station or porthgwidden beach, those are a good compromise. It’s impossible to park in the island car park in August so don’t be fooled into that. Barnoon isn’t much better.
fwiw even some ‘narrow’ spaces are ok as long as they are in a line from left to right and not abutting a cliff. I drive a Honda CR-V which is a fairly big car and it’s reasonably easy to park in our ‘narrow’ space just because the spaces are in a line.
