The wedding bit - 

is at the Town Hall, Ipswich, IP1 1DH. It is right in the middle of the town centre, so plenty of parking within a short walk. Here's a link if it helps.  And also, live availability information here.

You could also get the train. Get off at Ipswich and it's a 10-15 minute walk into town.

Joining us for the beer bit -

is at Milsoms, Hall Road, Kesgrave, IP5 2PU. It's nice! Plenty of parking, lots of grass, and bar for those not driving.

Maybe stay over for the night.
