Many people here have said this about 2 users not being able to book excursions at the same time on the same account. But, for us, this is not the case. We have always been able to book excursions at the same time. In fact we did this 2 months ago for our cruise next month We're travelling for 5 weeks, so that was a lot of excursions and it took us less than 5 minutes with both of us working on it.
