Suggest you contact any Ibis hotel in the Calais area, or possibly Campanile or Mercure - though they may be towards the top end of your budget. There is also a Holiday Inn in Calais - they may actually offer travel cots. All these hotels can be viewed and booked over the web. It's probably not worth investing charming B&Bs ...... you need them to be flexible enough to have 4 bedded rooms and used to English kids!!

Thanks for that, we have used Ibis ourselves in and around Paris but they had slipped my mind perfect for what they want and in budget,my daughter is at the moment trying to book fingers crossed

I was going to suggest the Campanile as well , we use them on our journeys up and down France for one night stop-overs.

The Ibis at Sangatte is the closest to the tunnel.

We're staying at Suitehotel Calais Coquelles Tunnel sous La Manche in August on our way back from Loire Valley.

Slightly over your budget at 111 Euros but it has great reviews and looks lovely.
We were having trouble finding anywhere that had availabilty for a room for 4 and had originally booked 2 rooms at Formula1 but came across the Suite hotel review on this site.

Ooh, ooh!
I know a good site - we used these guys when we went to Paris last December - french connections, I think it's co.uk not com ... not the clothes guys either!

I think they might be able to help.

I've stayed in Calais about a bazillion times - when I was little my dad worked for P&O and we went there every other weekend, it feels like.

My mum has a favourite anecdote - apparently when we went, all I would eat were laughing cow cheese triangles. And that was it, for a whole week, because I didn't like the frenchy food! So, maybe stock up on some, and dairylea too!

I hope I've helped, I'm new here, I would like to make some friends
