Hey Tina, Kasturi Bagh, ITC Rajputana, Clarks Amer, Rajwada Palace and Jai Mahal Palace are some of the best destination wedding venues in Jaipur. For more options, refer to the Tripoto blog attached below. However, with the coronavirus outbreak, I'd recommend that you refrain from non-essential travel right now. Stay safe! :)
Well, you may find the best resort for wedding in Jaipur but I know in Shimla you can get the best wedding destination for you. So, I would suggest Toshali Royal View for getting all the wedding facilities if you have any requirements.
