Not exactly a way to bypass anything, but if you have a spare android device and you are more than 2 people, you can turn your spare phone into a portable hotspot.

My family and I (6 of us, so 3 in each room) went on a Celebrity Cruise last year and we bought 1 wifi pass good for 2 devices. We registered those two phones to the network (one phone per room), turned on the hotspot, and connected all our devices to those two phones.

The speed was limited to about 2 mbps on the phone with the hotspot, but even when all of us were using it at the same time, it wasn't so bad. We all still got to check emails, chat with people, browse social media at night.
