I used vacation rather loosely. By vacation, that included visits to grandparents, and relatives, not just local and international trips. I qualified vacation as any time away from home, away from daily routine. So yes, it is the same. I have nothing against doing gymnastics while on “vacation“ if your daughter really wants to do it. I don’t know what time with her dad involves. She could be bored. So she might want to do gym.
I’ve been a member here since 2011 (I’ve changed usernames because I didn’t like the ones I first picked) and your question is one of the most common questions asked by parents during the early stages of their children’s gymnastics career. I’ve been there and done that and based on my own experience and what I’ve seen, two weeks away from gym or even a month doesn’t really affect your daughter’s gymnastics skills or strength.
