TCoys28, I thought I had posted an answer to this earlier. Through organising footie trips I've become quite proficient at using cheap airlines. What airports are near you and where would you prefer to fly from?
With £1,000 you could do loads, although America is probably stretching it. If you are looking at a 4/5 day city break in Europe the choice is vast. I would recommend Madrid, a truly beautiful city and easily accessible with Chessyjet. It is a much nicer city than Barcelona and you have three major museums all within easy reach of each other. Add in beautiful parks, the magnificent town of Toledo close by and the most amazing stadium in Europe, (Windsor Park excepted), and you could have a very happy hubby indeed.
Rome is great too, but Dublin is a tad expensive when you get there. Also Milan, Pisa, Paris, Munich, Riga, Krakow and Frankfurt. Book your own hotels through Expedia. When the Icelandic volcano went off I had my money back from them in full in three days. If you give me ideas and dates I would be happy to see what I can come up with.
The boss lady is taking me to Vienna for my 50th in November and we have spent about £450 so far. Just beer and food money now.
