Please don't rely on this if it is important to you to avoid bleeding on holiday.
Utrogestan is not strong enough to suppress any endogenous ovarian activity you are still having, so switching it about will not guarantee you a bleed free holiday.
If the objective is not to bleed on holiday you would be better getting a progestin that is indicated for postponing menstruation such as provera, norethisterone or a double dose of cerazette daily - the latter is not standard but less unpleasant to take and equally effective if started a few weeks before you go.
However you say that you wish to avoid taking utrogestan on holiday - if it is simply that the utrogestan makes you feel like crap and you don't mind bleeding, you just don't want to feel like crap, then just skip that course of utrogestan until you get back. You may or may not bleed.
If it is the latter then I would also say it may be worth considering alternatives anyway - why just feel good on holiday when you can feel good all the time?
