We hired Party Booths less than a week before our wedding as a last minute "extra." I am SO glad that we did. Our guests utilized it for the 2 hours that we hired them, and we got some great pictures! They were so prompt with getting them posted online, and our guests were able to access the site and buy pictures on their own when they wanted more copies.
They are very easy to deal with, the costs are plainly stated, and our attendant (Simon) was fantastic. He was great with the guests, set up & break down were easy, and he even took pictures for guests on their own cameras outside of the booth. People really get into the pictures, young & old, and you will have great moments captured. Plus, you'll be surprised by your friends creativity!!!!! We did not have props, but I can see how those would have been a great addition. Our friends ended up bringing their own props in :-)
You will be so happy if you have Party Booths at your wedding!!!
