When I went to Cairo, they took anything. But I'm not sure Port Said and Safaga are suitable places to be 'wandering ashore'! These are not tourist destinations. I should stick to excursions even if only ones to a hotel beach resort, if you don't want to do ancient history.
Thanks Rae and everyone - as always on this site, very helpful information. Colin.
The locals usually accept any paper money in Egypt some will even take euro coins....but Egyptian pounds are readily available in our Post Offices (you don't have to order from a main post office they keep them).
Safaga and Port Said are not really suitable places for "wandering about" you would be much better to have a look at what is worth seeing there and get a taxi for the day, they are cheap enough provided you bargain and they will take Icelandic Krona if you offer it!
Port Said has nothing to offer the tourist but there is a promenade and very filthy beach (not seen so much rubbish on a beach anywhere else) and locals have horse and traps to take you around if you want to see more. We have visited twice - the first time last year we got a tour to Giza to the pyramids with lunch on a nile river boat which was great and well worth the £95 charged by Fred Olsen cruises - then we have just visited last month on P&O Arcadia and as we had already done the pyramids we decided to have a walk on the aforementioned promenade. You will be swamped by locals trying to sell you goods and they accept euros and dollars (and as previously mentioned probably any currency), it can be a little annoying although I know some people enjoy it. Hope you have a good time.
