We did our homework and realised that we needed some professional, reliable help and found that Czech travel centre offered a great service at a good price. They immediately impressed by responding quickly to my e-mail and were incredibly helpful throughout. They were very patient when we hit problems with our paperwork and - obviously - had a thorough understanding of the UK and Czech systems. Allow a morning to go through the legalities in Prague (or wherever). The day itself was wonderful - a wedding in the old town hall, the ceremony conducted by a councillor of old Prague. An amazing experience. Thank you.</blockquote><div class="sign">Nicholas Bell</div>'
