My wedding reception marquee was about �3000 for 140 people, it had dance floor, tables and chairs, lighting, star linings at one end. It was fantastic I got it from Red Lion Marquees
What you need to work out is what you have to spend and then what is the best way of egtting bang for your buck / value for money. I used www.3dmarquees.com , as they were able to tailor their offering to my needs rather than just offering a standard off the shelf marquee hire package. I did the rounds of speaking to loads of companies, and yet these guys were the only one that really listened to me and worked to my budget
