If you are well and in good health by then depends on the destination I would say? Europe near cities/towns with proper hospitals should be fine I guess. Speak with your MW/consultant. Assuming you are good to go they will certainly advise you to check on hospitals in the area you are planning to stay. Also, make sure the airline you are planning to fly with will take you cause their rules for pregnant women vary.
I was fine at that stage to travel - but everyone is different. Do make sure you double check your travel insurance as well as the airline's policy. Some travel insurance has much earlier cut offs for travelling than the airlines do. Enjoy!!
It would also depend on what you're planning on doing on holiday & how hot it will be. I went to Tuscany at 26 weeks. The heat & walking round did get a bit too much for me on a couple of days. The days spent lounging by / in the pool were great though.
