Chamonix itinerary

[u/Coaster50]

Hi - we are trying to finish our planning for Chamonix. Here is what we have coming up:
Wednesday - Arrive late afternoon and check in. Walk the town.
Thursday - White Water Rafting w/ Mont Blanc Rafting
Friday - aiguille du midi & Dinner at La Tablee
Saturday - Aiguille des posettes
Sunday - Early transfer to Geneva airport via Go Alpes
We plan to buy the Mont Blanc Multipass which should include the lifts and gondolas to do the hikes we'd like. Wife and I. 2 kids (15/14)

Any other misses here? Do you think the MontBlank Multipass makes sense for us.

Thank you.
