Hi Flower041
I was in Porec for a couple of weeks in June 2010.
I stayed at the Mediteran Hotel just along the coast from the town.
Be aware - it's NOT a beach resort in the normal European sense - the whole coast is rocky with rock bathing areas.
However it's very beautiful, and the coastal cycle trail goes for miles and is superb for early morning or evening walks - or you can hire bikes at low cost.
I found Croatia really wonderful - the people are great. And there's lots to enjoy just wandering the streets of old Porec town.
Porec town centre seems to have some sort of celebration at least every two weeks. While I was there, there was a huge competition for majorettes going on in the streets - lots of colour and music - I really enjoyed it.
And spend some evenings in the town centre - the pavement cafes and street entertainment are fun.
Excursions - the best I did was the Hydrofoil across to Venice for the day.
A super day out, though eating out in Venice can be expensive - instead, I followed the locals, and just bought an excellent pizza and beer in a local bakery shop..
I also caught the local bus down to Rovinj - which is a lovely photogenic town. Great places to eat all over the place.
One word of warning - do not be at the top of the old bell tower at 12 noon. You will not hear anything else again for 24 hours.
Lots of one day boat excursions are sold along the waterfront in Porec town - and these are excellent also, with low prices and most include a good grilled fish lunch. Just walk along the front and choose the boat you most like the look of.
I went down to Pula for a day - again using the local buses.
I'd not recommend this - Pula isn't a really attractive town in my opinion, too much industry, and graffiti.
Hope you have as good a time in Croatia as I did - I will certainly return there soon.
