Singapore, Singapore
This plan is for Mum and Dad, the rest of us aren’t necessarily doing all of this the same as you. The overall dates will likely be roughly the same, as it makes no sense for us to not use the 1st and 3rd weekend when we could be in Asia, we may just not necessarily be with you.
For the remaining 4: Ryan may want to show us around Singapore. We can stay in different hotels of different budgets, but I think this would be nice. Grace and I will obviously have already been, but it is a nice place and we wouldn’t mind seeing it again with Ryan, however we may go somewhere else in Asia that has good links to Lombok (Kuala Lumpur).
