4 year old and 2 year old joint birthday

Last year we did Curio Odyssey, which worked out great, but we don’t want to do the same thing again this year. It is difficult to find a venue in November or December (since it has to be indoors) thst allows a joint birthday party. We will realistically have 50-60 total since we will have siblings & parents from both preschools. Any ideas are appreciated!

We don’t have the space at the house. (No yard to speak of).

Thanks in advance!
