It depends very much how you do it snd where you want to go to.

Basically if you are visiting the main tourist sites then it is not a particularly difficult place to visit. It becomes even easier if you pre book a tour with guides etc.

If you want to get off the beaten track then it will become more difficult, and travelling by bus or train can be a lot of hassle.

If you are looking for a beach holiday then do not that the Myanmar beach resorts are not very developed which can be a major plus for people but don't expect much for the kids to do other than build sand castles.
