I have been to Zwolle four times and plan on going again. I never thought such a show ever existed until I went. I was amazed at how huge this hobby is and the amount of scratch built and conversions on display. It is a couple of hours flight from Belfast and Dublin then another couple of hours on the train but it's definitely worth it.
It's location and superb transport links make it as cost effective as travelling to a show in England or Scotland.
I have never been to Spalding but I have seen plenty of photos. Unlike Zwolle there is nothing that would attract me to go to it. It looks more of a selling show.
Being involved with Moira Show in Northern Ireland I have often asked myself "what makes a show stand out and make it worth going to?"
If a show has something that bit special people will travel miles and hours to see it. Moira and Mitcheltown shows will have people travelling the full length of the country to take these shows in. This can be 4-5 hours. Then there are the diehards like Mr Softie who travels even greater distances.
I know we are in an recession but very few people will travel to Ireland for model shows.
I believe that there are a couple of shows in Ireland that are standing head and shoulders above anything in the UK. (Zwolle is no 1) I am not being big headed, I am just being honest. Speaking to many collectors, magazine editors etc, I always encourage them to visit shows in Ireland but its a struggle to get them to cross the Irish Sea.
