I just want to share our experience
when we planned our wedding, I am certain that I won't do money dance kasi feeling ko nga nanghihingi ng pera sa guest on the spot and pinaghandaan at nakapag save naman kami. naka-note na din naman sa invitation na money yung preferred gift. By that time my my now husband has an opposite idea and VERY strong feeling to do money dance kasi additional daw sa savings (and kuripot in a good way sya, lol!). inabot kami ng 2 months, kaka explain nya why we have to do it and here are his points:
1. prosperity dance is accepted in the Philippines
2. our foreign friends will experience a different culture
3. it won't be a hassle to our guest to find and bring a gift or visit our registry
4. we will save a lot
5. we can invest the money in stocks ( good point )
6. It's a fun activity for our guest ( he said, imagine if you're the one giving a gift and you know it will make a promise into reality, what would you feel? )
7. it's just a process of giving and receiving since marami kaming friends na single, eventually we will return the favor
8. we will have additional fund to share in the charity
So, I eventually agreed to have the dance. I'm really nervous before our host announce it. Praying like: God, why did I agree about this, please help us... ( haha! nakakatawa nalang pag naaalala ko. ) Our coordinator put a sash and he even gave ampao to our guests. Thankfully, game naman yung mga tao sa event. The gift amounted to almost 40% of our wedding cost. That's really huge, beyond expectation, hindi ako nakatulog. kahit yung mga officemates ko naligayahan sila.

I eventually learned that our coordinator told to our college friend's table na sila mauna para hindi maghintayan. good thinking on his part.
just some points and learnings on my part, iba iba talaga kung pano yung thinking ng mga tao. like me, I think nung una it's not okay but majority of the people and base na din dun sa outcome nung activity it's okay. your guests will not judge you just because sumayaw kayo ng 5-10 minutes.
Depende pa rin yun sa ikakasal kung gusto nyong gawin or hindi. If you decided to do it, dapat na-relay ng maayos sa mga guest nyo yung activity para ready sila. lastly, be thankful dun sa outcome kahit anong mangyari.
