It is a normal time to visit there. Also the thing about Singapore weather is that you can visit any time of the month.It is relatively the same whole year. For Malaysia-Singapore you can board a flight or other means of transportation are also available.I hope my answer fits your query.
I have only May as an option as I’m switching jobs & these are the dates in between. Do you suggest an alternative in the same region as an option ? And what if I’m reaching Malaysia first & then Singapore. Then would I still be charged something ? And lastly can one travel these 3 destinations via
This region is hot all year round. So does not make a lot of difference. Though I would suggest you visit Philippines.. May is generally less crowded and though their rainy season is about to begin but still you can enjoy some good sunny days as well.. Regarding the visa, I am not sure.. I went to KL on a transit flight and had to apply for visa seperately..
1). It is not the perfect time to visit in may but if you wish you can. but I'll suggest you to go in between December and January.
2) Singapore to Malaysia and then Thailand.
3) You between Singapore and Malaysia you can avail bus services.
