Hello Adrienne! (Yes, it's been over a year since you last posted but I had to comment)
I've read your trip diary, I loved it! I'm Portuguese so I have fun reading what people think about our country. I just wanted to let you know some stuff: Estoy perdida is wrong, estoy is spanish. In portuguese you say estou. (he-shh-toe) Camera is wrong, it's câmara. It's like city hall. Yes is sim, not si, again that is spanish.
I get the confusion, the languages are very similar, and people understood it, so no worries. :) Just thought I'd let you know.
You have to visit the Northern part of Portugal, there are amazing places to see!

@ Adrienne
What a great trip report. Loved it!

@ miss-tanya
We have visited your lovely country this June (Porto & the Douro Valley, Coimbra, Sintra, Lisbon, Algarve) and are coming back next year in June to explore other places.
What should we not miss in the north? We had plans to stay in the Braga/Guimarães area for 3 nights (which is better?), then further on to Obidos (3 nights - side trip to Tomar?) and Evora (3 nights) before we end up in Tavira again for ten days of relaxation.
Any comments or suggestions?

I'd say you should stay in Braga. You have to visit the Bom Jesus, it's so pretty! Then you could visit Ponte de Lima, Viana do Castelo, Guimarães or Póvoa de Varzim, they are all close. Póvoa de Varzim has nice beaches and people use to go out at night to walk around the Passeio Alegre, have coffee... very pretty.
Óbidos is amazing, but go to Tomar as well.

Thank you so much.
Bom Jesus is on our list. I added the other places you mentioned. Tomar is on our list, too. We'll do it as a daytrip from Óbidos.
Thanks again!
