Hi apprye, mine was 1-3pm oso.
as mentioned by raragal, the timing is the time to sign your paper. Wat we did was outdoor photo taking at 12pm. signed paper at 1pm, lunch at 1.15pm. once lunch served, we took more indoor photos with family and relatives. lunch was served till abt 3pm n everythig was done. if i am not wrong, PJ cant let us stay too late as they have to do closing and prepare for evening opening.
