[cwch]

Hi all,


My friend and I are planning to go backpacking in Mexico, Guatemala, and Costa Rica. We have had a rough itinerary, and hope people who have been to these countries can kindly give us some advice!

DAY

2 mexico city
3 mexico city--teotihuacan--mexico city
4 mexico city--taxco
5 taxco--mexico city--oaxaca

9 merida--uxmal--merida
10 chichen itza
11 chichen itza--cancun
12 cancun
13 cancun--playa de carmen
14 playa de carmen
15 playa de carmen--cozamal

17 tulum--chetumal
18--20 chetumal--belize city--flores--tikal

42 san jose --parque nacional manuel antonio
43 parque nacional manuel antonio
44 parque nacional corcovado
45 parque nacional corcovado
46 san jose
47 san jose--L.A--Taipei

And now we got some questions while planning our travel:

Q1: Since we don't want to stay in Belize, we are finding any possible way to reach Flores from Chetumal without going through Belize (the visa fee of Belize is too expensive for us). Is there any way to go across the north border of Petén, Guatemala by bus without having to going through Belize?

Q2: What is the price of the plane ticket fare from Guatemala City to San Jose provided by Guatemala City's local travel agency? The price we saw in TACA's website is about 200 usd (one-way), and again, it's too expensive for us

Q3: The spots we are going to meet in Costa Rica are too dispersively-located, and so for the itinerary in a mess (we just don't know how to arrange the itinerary in Costa Rica...). Can someone please give us some advice or even rearrange the itinerary for us?

Any comment is highly appreciated, thank you!!
