Surfboard for a beginner while travelling

I'm 5'6, 108lbs, above average fitness, female, still fairly a beginner.
I've had experience on a 7'2 funboard in Siargao (Cloud 9, which is a super awesome place and everyone should visit) and can pop up successfully 90% of the time and turn (with a lot of effort, damn the board was tough to manuveur) to ride the face of the wave instead of whitewater. Granted there is lot of room for improvement on my paddling and I have yet to grasp reading waves but I hope this comes with experience! Was there for about a week clocking in 4 hours a day on 3ft (4ft on the better day) waves.
I live in the city so there are no waves near where I am hence I usually take surf trips out to neighbouring countries. I'll probably only be riding small waves for a good long while.
So... I was thinking of getting a custom board in Bali (where I'll be heading next) which is about a million idr. As I'll be travelling quite a bit to Maldives, California and back to Siargao again I wanted a board that I can easily check in (probably max 6'2). Question is, would it be wise to purchase in my situation? And also would 6'2 be a suitable length? I know I should probably rent boards and get more time in the water but board rentals are usually ex unless it's places like Indonesia or Phillipines.
