cant speak for pueto del blackpool, but was in playa blanca end of feb and didn't notice any seasonal closures ect.

It's a large resort & mainly all year round so I'd imagine there'll be plenty open for you to choose from

PDC. is fairly busy in March. Restaurants, bars and shops are all open and waiting to welcome you. Look out for the meal and drinks deals, they can save you a few bob.
Calling it P. del Blackpool is a little unkind Stuart, if you prefer Playa Bournmouth, so be it.

ha ha we've never been to lanzarote but was hoping to avoid the fish and chips by staying other side of old town and harbour

i guess i will just have to see for myself

is playa blanca meant to be more upmarket then? or is it all much of a muchness?

Anyone who think PDC is like Blackpool either hasn't been to PDC or hasn't been to Blackpool.
