Garden Marquee Hire Question

Hello everyone!

I'm planning a backyard party and considering garden marquee hire to accommodate my guests. I want to ensure we have enough space, but I'm unsure about the best size for about 50 people. Can anyone recommend reputable companies or share their experiences with marquee rentals? Also, what features should I look for when hiring?

Things like flooring, lighting, and sidewalls are on my mind. Any tips on setup or additional items I might need would be greatly appreciated!

Thanks in advance for your help!
