Advertisement For A Birthday Party Venue

I saw an advertisement for a birthday party venue, so I stopped an attempted to read it. Even with my Thai dictionary, I still had trouble. Here are the sentences (there may be some errors). The online translator was not able to give me a good translation.

ถึงจะโตขึ้นอีกที่ปี จินตนาการความสดใสก็ไม่มีวันสิ้นสุด สนุกเต็มที่กับปาร์ตี้วันเกิด

Even though (you,they, etc) will grow up another year

Imagine cheerfulness that never ends

Fun filled birthday party

My translation is just to give you an idea of my initial thoughts. Would like to have a better translation than the one I came up with.
