Cost of 10 Day Honeymoon in Europe by TA?

Hello,

We recently approached a Travel Agent for our customized Honeymoon Trip to Swiss and Italy for 10 Days in Feb 2025. They are quoting us about $11K for 2 person including 4 star hotels, Private transfers from Airport, local transport and breakfast. It does not include International flights, Meals and other activities that we plan to do there. We really like the Itinerary they provided us. I checked the hotels and the train routes. Hotels does not cost more than $300 for a day for 2, and train rides are not more than $100. We are wondering if the TA is overcharging us premium amount for these services? What other costs do they add up to make up for $10K? Is it really worth it?

Thanks in advance.
