If you are looking to cut cost when it comes to the reception location, why not choose to have it at a hotel. Most hotels have large halls therefore able to accommodate large parties or make accommodations for smaller ones.
Plus, the hotel most likely will throw in the honeymoon suite if you book with them. They may be able to give you a group discount for your guest’s room rentals.
Some hotels may even have decorations such as tulle or chair covers available to rent. So remember to ask!
