Hi, welcome and thanks for writing in.
Rare side effect of doxycycline is photosensitivity. It is seen in long term prophylaxis for any condition like malaria prophylaxis. It seen in only 1% of individuals.
Doxycycline has half life of less than 1 day. It means single dose will get cleared in maximum 2 days from body.
You can enjoy your holidays without any hesitancy. There is sufficient gap between the treatment and holiday. It will not cause any serious side effects.

Hope I have answered your query. If you have further concern, please let me know.

Regards.
