Just finalising the big trip. Need to get from Llandudno to Manchester to catch flight to Dublin which we have booked. Flight leaves at 10:50 am. If we catch train from Llandudno how much time should we allow ourselves and how difficult is it to change trains at Oxford road. We are in our 50's and not as agile as we were and don't want to run too fast or far.Have looked at lots of train sites as well as seat 61 and raileasy and need to finalise. Thanks.
