Middle School Latin Trip to Rome

Does anyone have any experience organizing a middle school Latin trip to Rome? I am interested to hear from people who have gone to Rome with language or culture institutions. We are thinking of a week/ten days during the spring break.

Conversely, if you have experience leading such trips independently - any tips? We are interested in Rome and the Vesuvian sites above all, but can we make it to Sperlonga, Tivoli...?

Any advice would be wonderful - thank you!
