Me & my wife are visiting Singapore & Malaysia for a 14 day trip. We have a 9 week multiple entry visa for Singapore and 1 year multiple entry visa for Malaysia. We am planning to stay at my friend's home in Johor. I would like to spend most of the trip in Singapore (since we did visit many places in Malaysia last year).
So, ideally, around 7 to 10 days we would like to be in Singapore. So, that means, upto 10 border crossings each way - morning from Johor to SG and night time back to Johor.
Is there a chance that we will be denied entry after x times? If yes, what is a safe number of crossings? This is purely tourist visit, so, I am hoping that this is perfectly legal and we can spend more time seeing Singapore without the hotel cost :).
