Just finished a month trip to Portugal and Spain. Great trip.
Portugal should be on a short list for budget trips to Europe. Seriously, even expensive Lisbon, good value hotels and food can easily be found. Seemed like everywhere we could find a glass of wine for under 3 euros. Crazy. And the food is outstanding. Very seafood oriented, but there's plenty of options if fish isn't your jam. I would also encourage anyone to go to the Time Out Market, which is in the old market building. Some utterly amazing food for really amazing prices there. It's hard to describe the options you have there, but suffice it to say, this is not a secret at all- it was packed the times we visited.
We also went to Porto and had an excursion up the Douro valley. Same kind of story as Lisbon in term of food and wine. Quite a bill hillier to visit than Lisbon was, but some interesting stuff to see. I kind of wish we looked for more museums in both cities, but we didn't.....
After that, we went to Tui to start our Camino. We were part of a group where they provided hotels and moved the luggage for us, and I have to be honest that it was not really worth it- it's not hard to put a reasonable Camino plan together so you can book your own hotels. The route is pretty cool in that much of it are old Roman roads, with huge ruts in the rocks due to the many centuries of people using these roads. I personally didn't get anything out of the pilgrimage nature of the trip, and actually it put more gap between me and any church. But YMMV. Our walk was the last 118km, and could have doubled that starting in Porto. We *might* do another path in the future, but certainly not for religious reasons.
Then we worked our way down the coast back to Lisbon- Vigo, Vianna de Castello, Obidos, and Sintra. Most of that we had a great time exploring different places, and it was cool to get a bottle of wine for our hotel room for 5 euros, which was the middle priced one....
Obidos was really cool, I have to say- it's kind of a tourist trap, but it really is quite old, and you can see that all over the place. And in the last decade, they have gone out of their way to be a literary destination. Pretty creative way to bring people, if you ask me. We happened to be there at the beginning of a literary festival, and had a great time.
On the other hand is Sintra. Didn't much care for this. Other than one place that is truly historic, every single main attraction is totally fake. All done in the 19th century to bring people to the area in pretty questionable ways. And it's REALLY FREAKING CROWDED with people on day trips from Lisbon (which is really close by). Food and wine are expensive here (relatively) and just ok. The one real place is an old moorish fort at the top of a mountain. Which also had some settlement evidence from thousands of years ago. Other than that one thing, this is just a really old tourist trap.
The trip home was interesting- our original fight home was canceled, so we got a bonus Lisbon day. And *maybe* will get some significant compensation for it. If that happens, I'll let you know because it's an EU rule and the cause was a mechanical problem with our plane that never left Boston.
