About 3 weeks ago, a guy I used to date "Jeff" and I decided we wanted to go to Europe/Portugal for a week. We knew right away we would be spending an arm and leg to, but this was both something we really wanted to do. Since vacations are better when more people are around, we asked all our friends if they wanted to go. Everyone said no, so after 2 weeks, we went ahead and booked our tickets and hotel (a single twin bed). Three days ago, I told my best friend "Melissa" that Jeff and I had booked our flight/hotel. She mentioned she was jealous, etc. We had originally invited her, but she declined because it would be too expensive. Today I get an email from her saying she wanted to go after all. I feel really annoyed. If she goes, 1. We have to share one twin bed while Jeff sleeps on the ground. The hotel is crappy and does not have any couches, but it is centrally located. If she had told me before, I would have booked a double bed. Now it is too late since I used expedia and it is already paid for. 2. Since her flight is on a different day, we would have to meet her somewhere in Portugal. None of us will have working cell phones and there is no way of knowing if her plane lands on time. I don't plan on staying at the hotel much, just to sleep and shower. 3. Melissa can be very judgemental and bitchy and constantly uses the restroom. I've gone on road trips with her and can't stand her for more than 3 days. 4. Melissa will probably complain about money and not want to spend any while we are out and about. 5. She will probably make fun of my crappy Portugese. Both her and Jeff are Brazilian, so they speak it fluently. I am Vietnamese so it is not my native language. I've made an effort to learn Portugese, but still am not fluent. 6. I was hoping to rekindle the romance between Jeff and I, but with her along, it will be very hard to do so. Should I go ahead and tell Melissa she is not welcome? And if so, how do I do it? Or am I just being petty and I should let her come along? She's been a friend for 9 years and I don't want to cut her out of my life.
