Spain and Portugal pair well because the food, the late dinners and the coastal light are shared, but the logistics differ. Barcelona is a compact city break, mainland Spain works as a two-week loop, and Portugal is small enough to cover in a week.
Use these guides to pick your cities, understand how the high-speed trains work, and decide where a beach island like Mallorca fits in. Each guide includes realistic daily plans and neighborhood-by-neighborhood hotel advice.
In Spain, the AVE high-speed trains make Madrid, Barcelona, Seville and Valencia easy to link, and booking a few weeks ahead keeps fares low. Portugal is best on a Lisbon-and-Porto spine, with a side trip to Sintra or the Algarve.
Meal times differ from the US. Lunch is the main meal and dinner starts late, so plan your day accordingly.
