Where to yo after visiting sevilla. Need help deciding on villamour or porto for 3-4 nights.

We will have already traveled from barcelona to sevilla. We will spending 4 nights in seville (is this too long) and are torn on where to go next. We will be flying out of lisbon and have a few days to play with there. The convenience of getting to villamour and being close to beautiful beaches sounds appealing. As well as paying with points for our accommodations.

This will be our first time in europe. We had originally planned for porto but getting there does not seem as easy from seville. As well as everything seems a little more expensive.

Any input is welcome. YES!! I know they are 2 different vacations. We love both the beach and wine. We are open to both. We will probably not return to these countries so where should we spend that time? Open to other locations as well. Travel fir this would be the first week in September Is Ryanair the best option from sevilla to porto? ** not sure this information is important but we are not high maintenance travelers but not backpackers either lol

TIA
