What do I need to reserve in Rome?

Hi. We will be in Rome for a week soon and although I have a fairly good idea on what is there to be seen and done, I hope you can help me by saying if there is anything for which I need to reserve in advance. Any tips on where to go are still welcome of course. We are a couple with two kids. Thank you.

Hi. Get yourselves Rome Archeological Cards. These are great they give you access to all the main sites in Rome at a reduced price, and not unimportantly, without queuing. The Card is valid for seven days. Reduced price Cards are available for residents of the European Union. Kids go free if they are EU residents. For other kids, this goes until they are 6 years old.

Hi,
Rome Archaeological Card is a very handy thing and it's ease to get. You can book it on-line. With it you can see main archaeological sites as The Colosseum, The Crypta Balbi, The Diocletian Baths,The Palazzo Massimo, The Palazzo Altemps, The Tomb of Cecilia Metella, The Terme (baths) di Caracalla, The Villa dei Quintili, The Palatine Hill. Thees places can be crowded so it is even recommended that you have the Card.
