Destination wedding , when do i send out the Invites?

We’re having a destination wedding on June 05 2025 in Puerto Rico we are sending out our save dates this week , when should we send the invites for the wedding ? And when should we get the RSVPS back so that we have time to let the vendors know especially when we have may need extra tables for rentals , caterer and desserts since guest list is about 125 ppl and most likely about 90-100 will attend. The spot already holds 200 guest so that part is no biggie.
