What lens to bring to Spain and Portugal for travel?

I'm not selling my photos so the only person I have to please is myself. I've opted for a 28-300 Tamron, the 12-24 Sigma, the 50 1.4 and a tripod.

Not that I don't love the results with the CZ and the G, just getting too old to haul them around for the extra qualities that only I, and some of you, appreciate. Friends and relatives?..they ooh and ah regardless of which lens I use.
