Birthday Party dillema...

I have read an article at Smart Parenting about How to plan your Kids Party. And now I'm pressured. My Hubby wants Luau... Ailey loves Little Mermaid and Kuya suggests Princess he said "Kse Little princess ko sya eh." As for me, I want Little Mermaid because she is my favorite chartoon character too but I don't know what to do with the decoration, as for Luau, I have everything in mind. And the venue will be at our clubhouse where there is a pool. Ha! Time is ticking! What should i do? Dydy is the MONEYGER while Ailey is the CELEBRANT and Kuya Jazer is the FOREVER STAGE KUYA! So please help me! I need your comments and suggestions.
