I just found out my daughter's 30 member Science Olympiad team is staying at a Courtyard next month, so being overrun with youth teams can happen. You have been warned.
To be fair the SO team tends to spend the night before the event frantically quizzing each other rather than running wild through the lobby and pool.
We like certain Courtyards, especially when like above, the price is so far below the FS Marriotts in the area that breakfast is a wash. For example- we like to stay at the Gas Lamp in San Diego but if Liberty Station is 100 dollars cheaper, we go there.
