Starting to regret venue choice

Hello everyone! I think I need some advice and reassurance with my venue choice. Kind of a long post.

My FH and I are on a somewhat tight budget. Back in March, we looked at probably 20 venues in the area, and all were pretty expensive. We decided on a golf course with a beautiful outdoor ceremony area (with a cute indoor backup) and an AMAZING package deal for the reception! Our wedding will have around ~200 people and will be on September 26, 2020.

However, now that a few months have passed, I am starting to worry that the indoor reception area isn't all what I had imagined for my wedding day; it's a banquet hall with no windows, no tall ceilings, just kind of plain. I'm starting to feel anxious about my choice and wished we had gone with something different, or that I had looked into different venues other than golf courses. I keep seeing pictures of beautiful venues with tall trees, big windows with natural light, and beautifully decorated, and I just feel bad about my venue.

At this point, we wouldn't be wasting a ton of money booking a new venue. However, we want that exact date (it's our 10 year anniversary) and I can only be sure that all the venues in the area are booked for that day. I feel so embarrassed for even feeling this way towards my venue. I am going to post pictures of the venue in the comments to get some opinions on how to decorate and maybe get some reassurance that it's not so bad. Again, I feel embarrassed for getting to this point, but I just want my day to be beautiful and perfect. Thank you all.
