If you’d like to reach Xiamen at last; you could go to Xian first and then Guilin, last Xiamen. From Shanghai to Xian, you could take a night train such as Z92 which costs about 14 hrs. From Xian to Guilin and Guilin to Xiamen, you could take flights. For the shanghai acrobat tickets, you could consult some locals since the fare varies from seats and time.

Is that the hotel Holiday Inn Shanghai Vista or Holiday Inn Express Putuo, Shanghai? Anyway, from Shanghai Pudong airport, you could take the airport shuttle line 5 to the railway station first and then take a taxi to the hotel. If you take a taxi from the airport directly, it costs about CNY160 to the hotel.
