How fun!
Our daughter had limo parties for her 10th and 11th bdays and they were so FUN.
We used Allen Limo (I believe Rafael is the owner, I always talk to him) and were very happy. They have a website you can check out www.allenlimousine.com ###-###-#### Keep in mind, most limo services require a time limit of 2-3 hours. I think we spent about $300 or so. Also, you are limited on the number of girls for limo seating...(about 10) I don't know the going rate now. We are regular customers of Allen Limo for the town cars, etc to the airport. They are a good reliable source.
To use the time, the limo started at our house with daughter and myself. (Dad stayed home to prepare for pizza party and craft set up) We went to each guest's home to personally pick the guest up. Each girl was sleeping over so the driver took care of her things. I took lots of pics and each family got to take pics of the limo at their home and their daughter. After everyone was picked up they drove around Plano, through the Cinemark parking area, to popular places, etc and he would stop so they could stick their head out the roof. After the ride, they came to our house, had pizza, made crafts, movies and sleepover.
The 11 yr party was much the same except instead of sleeping over at our house, we went to the Marriott at the Shops of Legacy where I had a suite rented. The girls had 1 room and I had the other. We walked around the shops of legacy area, had dinner at Nicola's, then went back to the hotel, they swam, then went back to room to do manicures/pedicures, watched movies and then had late night room service. The next am, hubby brought in fresh donuts, juices and milk for them.
Since then, we went on an adult outing in the area and a limo Hummer was used. That was a lot of fun and if you have that option and it not TOO pricey, they girls might like that as well.
Hope this helps....Enjoy!
