How do you say "There are bound to be...."

Question

How do you say "There are bound to be...." as in "There are bound to be a lot of people at the party", "There are bound to be some exceptions to the rule."

Answer 1

To add to Heidita's note,...

I think this expresses in future tense how I would say, "I'm sure there are..."

*Seguro que hay ..."

Either way we're using haber.

Answer 2

HI dibra,

Seguro que habrá....

Sin duda habrá....
