What is the correct grammar- thanks for accomodation for the celebration tonight?

First, you cannot say "thanks for accommodation." It would be "thanks for the accommodation"-- but it still wouldn't make sense. Are you saying you are grateful you were invited to the celebration? In that case: Thanks for inviting me to the celebration tonight. Are you saying you are happy there was enough room for you to attend the celebration? That could be: Thanks for finding some room for me to attend the celebration tonight.
