Our flight from Mexico City to Cancun was overbooked, so we had to wait for the next flight out, an extra 2 hour layover. It doesn't sound too bad but at this point we had been traveling for 20 some hours, so we were exhausted. Once we got to the hotel, the guy checking us in sold us on an upgraded (better view, room service, etc). So they gave us a room with a view of a building and parking lot. Yeah no, that is not an upgrade from a garden view. So they took us to another room, with a view of the garden. Whatever. We were exhausted at this point and just took the room.
A little bit later we went to the hotel's beach and relaxed. Well then BF and I got into some stupid fight (don't remember what now) because we were both tired and cranky. I was so upset, I didn't realize that I had thrown my phone onto the lounge chair next to me, instead of putting it inside his backpack. Well we got up and went back to the hotel room and 5 minutes later I realized my phone was not in his backpack. We ran back to the beach, and my phone was gone, so someone stole it. Awesome. I was so tired and upset I just cried and cried in our room for a full 15 minutes while BF tried to comfort me. At this point, I was ready to just cancel the rest of the trip and go home.
Next we realized the phone in our room didn't work, so no room service for us. We went to the front desk and told them, and they said no one could fix it until the day before we left. Great. Ended up no one ever came to fix it.
The second day, I got stung by a bee. Awesome. What else could go wrong at this point? Well, we went to dinner that night at one of the hotel's restaurants and after dinner went outside to take pictures on their balcony overlooking the ocean. And then BF popped the question!!!!!
I was not expecting it at all! For a week or two before the trip he was dropping all these hints that it was definitely not going to happen in Mexico. So I believed him and accepted the fact that it wouldn't happen on vacation. So needless to say, the rest of the trip was awesome. The next day I swam with dolphins, and we pretty much relaxed the rest of the trip.
TL;DR: First two days of Mexico sucked, until BF proposed!
