More Money for a Bigger Space? Guest comfort or budget?

Hi all! I need help with an important decision. I found an all-inclusive location at $41.50 a person that includes food, open bar, linens - the works. However, the space comfortably fits 80. I have 107 on my guest list and have placed my date on a Friday to save money. This location also has two other ballrooms that could potentially be used at the same time. Although we could make the space work, I'm a bit hesitant to not have flexibility in the space - so we found another venue that was larger to tour. It is almost twice the size and has a bridal suite to get ready in, is the only room on location for a reception, and is a tad bit closer to home. This would add about $1,500 to our budget. What are your thoughts? We like them pretty equally in terms of their aesthetic.
