We'll be flying out of "London" this May via the SEN (Southend) airport. It looks like we just catch a train at the Liverpool Street [ed.] Station, yes? Is there anything special to watch out for? It will be a Tuesday and mid-day-ish.
We're not anticipating anything 'odd' but this is RyanAir (who taught us that "Paris" is "Beauvais"!) so there is usually something to watch for! Thanks.
