Invitation wording help

I need help!!
I have a problem with with wording my invitations. Please let me know if this is good?

Bride and Groom
with their parents,invite you to join
in the celebration of their marriage, on
Saturday, the fourth of June
two thousand eleven at half-past eleven at
Land's End
80 Brown's River Road Sayville, NY

I feel something is wrong with this, maybe a period somewhere or something. I have a limited space on the invitation.
TIA!
ETA: If the wedding is 6/4/11 what date do I put for RSVP?

Do you have one more line? Could you do:

Together with their parents,
Bride and Groom
invite you to join
in the celebration of their marriage.
Saturday, the fourth of June, two thousand eleven
at half-past eleven in the morning
Land's End
80 Brown's River Road Sayville, NY

If you're including a direction card, you can put the full address of the place on there. On the invite, 'Land's End, Sayville, NY' is sufficient.

Also, if you want to save space with the date, you could write it as '4 June 2011' or something

ITA!

Thanks, that's a great idea! I didn't think of the direction card. I knew I count of LIW Brides!
