We were staying at Kidani and attended the Beach Bash. There were 19 vacationing in our party and 16 of us went to the Bash. We got our bands from the desk at Kidani before we left and they gave us a little flyer showing what all was available and a map noting the locations of things. There was a Cruise Ship Charter bus that picked up those in our party that were at the bus stop at 8:00. We arrived just as they pulled off and by about 8:15 a regular Disney bus picked us up. So, some in our party arrived before 8:30 and were allowed in as soon as they arrived. They waited for us at the gate and we arrived around 8:35. They did have pool towels available for everyone walking in. By the looks of the crowd, I believe they allowed people in well before 8:30. We had to walk a way to find empty chairs. Our group spent quite a bit of time in the wave pool, then went to the lazy river and then started on the slides. I stayed at the chairs to keep tabs on where everyone was (okay, really, I was just tired and didn't have the energy to do much). Some members of my group mentioned having Mickey bars, others had cookies and lemonade and others had chips. The cast members working really seemed to want everyone to have a good time. It was a little more crowded than I was expecting, but the crowd after around 9:30 was more spread out and it didn't seem crowded at all. Our group left at different times during the night. i stayed until 11:30 with the last of our people. There was a charter waiting for us, however, it did wait until it was full to leave, which took a little while. Our group of 16 all enjoyed their time there and I thought it was a fantastic night!
