For my 13th birthday party, I got a Hotel Seepover with a "complimentry spa" at my house.  I invited 3 friends and gave them a reservation number for a "reserved room".  They couldn't "check into the Hotel" until 3pm and they had to "check out" by 10am. For fun I numbered all the rooms and labeled a girl and boy bathroom. I even made a room directory to hang in the hallway.      We played in my pool for a while then we got changed in my play room which became "our room". We then went to the "Dining room" and my brothers seated us and waited on us and they even gave us a printed up menu with lots of choices for food. After that we hung out in our "room" and just talked until 6:00. When it was 6, we went out to the Living room or the "Main Lobby". I opened my presents and my mom planned a special surprise.  In the "dining room" there was an "Ice cream Bar" with 3 kinds of ice cream and caramel and chocolate and candy toppings.      After that we took a little dip in the pool again and waited until 7:30.  At 7:30, we went into the "Spa room". When we got into the "Spa room", I gave my friends their party favors. For the favors I got everyone a washcloth. I wrapped lip gloss, a nail buffer and a bottle of nail polish in the washcloth. I also clipped a hair clip on the top. My mom buffed, and polished our nails. After that, my mom gave us a facial mask. This, by the way was, a big hit!     Then we got back into the pool and sipped lemonades. We talked and took pictures and waited until 9. At 9 we watched a movie. When it got done (which was really late) we got into our sleeping bags in our "room". Then when we woke up we had breakfast, with my 3 brothers serving us again. Then it was time to go.  This was a really fun birthday party! My friends said it was the most fun party they had been to! Hope you can do it!  This probably would be better if you invite only a few people.
