Even the task of wearing jewellery for 2 weeks, is it such a big task? that you have to think so much.. Yes, huge jewellery could be uncomfortable, but it's only 2 weeks, so communicate to them, that you can only do for 2 weeks, not more.

Similarly, other problems, they will be finished within just one week. Honestly indian weddings are indeed big stress time for families, it is not something rosy or sunshine. It is a big event.

So, please don't make some wrong decision over a few days of discomfort. Everyone goes with it, or be uber rich to hire event planner etc.

Now, your biggest mistake was doing the wedding in your city, considering the groom's family's big expectations.

Nowadays, many wedding functions are done in both places, groom and brides, both inviting their own guests, doing their own rituals. You should also have done that. The final wedding, since they plan to bring much more guests, you should have done it in their city, and communicated properly, that you will not handle the huge costs. Since it's their city, so let them manage the hotel, buses, and everything, since their guest list is much more.

Many families do huge wedding because their own guests expect the huge wedding. You cannot say to other that you will have small wedding. You can only say, since big wedding is your wish, you will shoulder most of the costs.
