Trip to spain

Aloha ,

Advice please . We are hopefully looking to travel to our plot near Palomares in Febuary flying to either Almeria or Alicante and hiring a car yhere it will only be 10 days just to try to sort stuff out as we havn't been for a while .

Could someone give me some guidance on what i need to take legal wise , we have had our third jabs .

Thanks for any help you can give .

Bob
