We have never done a back to back but prefer 14+ day cruises.
We are booked on the Oasis for next May. Since it is a 7 day cruise, we have been seriously thinking about booking the Allure for the following week. Since the Oasis is Saturday to Saturday and the Allure is Sunday to Sunday, we would get off the Oasis Saturday, stay at the Embassy Suites - wash and iron clothes - then Sunday board the Allure. Are we crazy? Would it be better to just stay on the Oasis for another week or try the newest ship too? It would be Eastern then Western but we have been to the ports so that is not important. Opinions???
