I think any change in location is relaxing in itself!! Just breaking the grind of daily routine etc at home is a holiday kwim?? Yes it's a bit more challenging travelling with a young child, you have to be more prepared than you ever were when it was just the two of you but it's really not that much harder. If you want to go away, then do it!!

We took our DD away in Dec to Fiji, at the time she was only 10.5mths old, only crawling at that stage so that was easy as she wasn't walking yet, but still very much a velcro bub as she couldn't walk then!! BUT, we had a wonderful time and couldn't imagine not going away without her! We had a fantastic time and it was relaxing..... mind you, we always had someone holding her as in Fiji they LOVE babies and want to carry them and take them off you so we didnt mind one bit hehe
One night we had the hotel nanny mind her (got a great recommendation from another happy guest who had used her!!) and they are Fijian mothers themselves so we felt safe with her, and we could go for dinner that night alone!
you will manage.

Good luck and have fun!!!
