I suggest check po muna if (1) makakalabas sila ng QC and makakapasok ng Pangasinan. With rising cases po kasi, baka masmaghigpit sila. And (2) kung approved ni OB. Land travel naman po so relatively safe, kailangan lang hindi dirediretso ang byahe and safe ang daan.
Then look into safe options po para makatravel sya nang safe. If she's using public transportation, she'll be with other people with several hours.
If possible po, break the travel time into one or two hours at a time, depende sa recommendation ni OB. Para may time sya na makapag stretch, and rest sa byahe.
Sana po magawan nyo ng paraan. Good luck po.
