As we do not have a lot of relatives, we hosted the full month party at private dining room at restaurants, about 1 to 2 tables. If you have a lot of guests, you can consider hotel's function room, condo function room, community centre/club function room, chalet, and etc.
I hosted it at the void deck of my house to minimise the mess and crowd as my house is not big enough. It can accommodate more people and there is a playground so kids can run about and play when adults are busy chatting.

My cousin simply booked the condo function room. She had a small bouncy castle (placed near the entrance of the function room) which helped kept the children entertained.
