The question is very extensive and requires detailed elaboration. When it comes to such a special event as a wedding, we treat selection with special care and attention. From your question it is not entirely clear what your budget is allocated for the trip - modest or on the contrary - unlimited. Eagle or tails:)

I will give an example of one pair who recently traveled with an average budget. They took a week-long group tour around the country, on a day off from the excursions they ordered a photo session for memory, so they traveled the whole country and got the maximum of impressions, and then flew to the island of Madeira, where the excellent Pestana Carlton 5 * hotel was spent a few days. We upgraded the category of rooms and gave our recommendations regarding restaurants, excursions.

Given that you have only a week, you can take a tour of the abbreviated program with a visit to Lisbon and Porto, 3 days to rest in one of the best hotels of the coast. Which depends on your preferences. There are modern ones (Cascais Miragem 5 *, Oitavos 5 * in the villa for the honeymoon, Troia Design Hotel 5 *, Farol Design Hotel 5 *), but there are old, arranged in family manors, palaces with their own unique history (Albatroz 5 * Fortaleza do Guincho 5 *, Grande Real Villa Italia Hotel & Spa 5 *, Palacio Estoril 5 *, Tivoli Palacio de Seteais 5 *).

You can also take a few lessons of surfing or golf, enjoy relaxing SPA procedures for two.

If you want to travel by car or public transport, then you yourself hardly have time to see everything, so you can move around on high-speed lektrichke (or high-speed road car) from Lisbon to Porto and back. In Lisbon, I recommend several options: Altis Belem 5 *, Avenida Palace 5 *, CS Vintage Lisboa Hotel 5 *, Dom Pedro Palace 5 *, Pestana Palace 5 *. Porto is the InterContinental Porto Palacio das Cardosas 5 *, The Yeatman Hotel 5 * De Luxe.

In Lisbon, there are good fish restaurants on the banks of the Tejo, for example "5 oceans". In the center of the city there are as many of them in the districts of Byro Alto, Baixa, for example. If you want something romantic and national, I recommend you visit a fado restaurant in the Alfama district

In Porto, try stew in port wine or a rabbit on the waterfront and always go to the pedestrian street of Santa Catarina in the old cafe "Majestic".

Take a walk in these cities, in Lisbon, go to Sintra, with its palaces and parks. Time will fly by unnoticed, impressions will be most pleasant.

I wish you a good rest and a good mood!
