Honeymoon in Portugal/Spain Recommendations Please

Hello,

I'm planning to go to Portugal and Spain for honeymoon this upcoming September I would love to hear your recommendation for hotels and the best itinerary for 12 days.

Maderia was on the plan, but I chose Algarve to reduce wasting time in airports.

Portugal

– Lisbon

– Algarve (Belmar Resort)

– Porto

and travel from Porto to Spain

Spain

– Barcelona

– Sevilla

– Madrid

I would also love to hear some of your fav cities or towns

thanks
